If I use apt on ubuntu to install python3-pyqt5 and then remove it, it leaves an empty namespace:
```
$ python3
Python 3.8.10 (default, Mar 15 2022, 12:22:08)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt5
>>> import PyQt5.QtGui
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.QtGui'
>>> PyQt5
<module 'PyQt5' (namespace)>
```
After some consideration I am fairly certain there is no need to take
wallet.lock in `is_up_to_date()`. Any caller that might want some kind
of guarantees re the value returned by is_up_to_date() would need to
enforce them itself by e.g. taking wallet.lock around its critical code
block. That is, even if is_up_to_date() itself takes the lock, between
the call returning and the caller reading the value there could still
have been a race.
Also, the GUI was directly accessing the field already.
note: `pip install ".[crypto]"` needs quotes on macOS, at least in the default `zsh` shell.
The quotes are not needed on Ubuntu using bash, or on Windows using powershell.
```
user@users-iMac electrum % python3 -m pip install --user -e .[crypto]
zsh: no matches found: .[crypto]
```
wallet.thread was serialising the fut.result() calls, so consider e.g.
- coro1 gets scheduled,
- wallet.thread waits on fut1.result()
- coro2 gets scheduled,
- coro2 finished with exception and wants to show an error popup,
-> wallet.thread is still waiting on fut1.result() before it looks at fut2.result
fixes https://github.com/spesmilo/electrum/issues/7750
Each task we schedule on `TaskThread` can provide an optional `cancel` method.
When stopping `TaskThread`, we call this `cancel` method on all tasks in the queue.
If the currently running task does not implement `cancel`, `TaskThread.stop` will block
until that task finishes.
Note that there is a significant change in behaviour here:
`ElectrumWindow.run_coroutine_from_thread` and `ElectrumWindow.pay_lightning_invoice`
previously serialised the execution of their coroutines via wallet.thread.
This is no longer the case: they will now schedule coroutines immediately.
So for example, the GUI now allows trying to pay multiple LN invoices "concurrently".
- the mac build broke with 184e122c36
- upstream fix is at https://github.com/pyinstaller/pyinstaller/pull/6701
however, we are using an old version of pyinstaller atm, so this workaround is easier

This allows more freedom than using releases from PyPI.
(atm there is no released version that fixes https://github.com/pyinstaller/pyinstaller/pull/6701 )
Also, we now build the pyinstaller bootloader, just like in the windows build:
one fewer binary blob to trust.
- the windows build broke with 184e122c36
- upstream fix being pulled in is https://github.com/pyinstaller/pyinstaller/pull/6701

Use refresh_row() for address, utxo and contact lists.
Replace unneeded calls to update_tabs() with refresh_tabs()
Fix right-click menu after selecting multiple addresses.
Swaps (both reverse and forward) are displayed in the list as a tree, which can be
expanded/collapsed. When expanded, double-clicking on any of the children (regardless
of child being LN or onchain), was interacting with the incorrect item (the first few
items in the top-level list).
Consider `self.tx_item_from_proxy_row(idx.row())`.
`idx.row()` is probably a small int, e.g. `0`, and `tx_item_from_proxy_row` is just
getting that item from the top-level list.
Note that the right-click>"View ..." context menu behaves correctly, so prior to
this commit it was inconsistent with double-clicking.
e.g. this text:
"This transaction requires a higher fee, or it will not be propagated by your current server. Try to raise your transaction fee, or use a server with a lower relay fee."
is too long for a single line.

We should delete `usr/lib/python3.9/config-3.9-x86_64-linux-gnu/` (which is 33M unpacked)
With py3.7 (electrum 4.1.5), this folder was named `config-3.7m-x86_64-linux-gnu`,
presumably because the default config to compile py3.7 was `--with-pymalloc`,
but maybe it is not for py3.9... ? not sure. (see https://peps.python.org/pep-3149/ )
