cli: allow specifying --wallet at any arg position, as before

Before commit 46ffab0b55 all of these used to work:
./run_electrum -o signmessage tb1qeh090ruc3cs5hry90tev4fsvrnegulw8xssdzx "asdasd" -w ~/.electrum/testnet/wallets/test_segwit_2 --testnet
./run_electrum -o signmessage -w ~/.electrum/testnet/wallets/test_segwit_2 tb1qeh090ruc3cs5hry90tev4fsvrnegulw8xssdzx "asdasd" --testnet
./run_electrum -w ~/.electrum/testnet/wallets/test_segwit_2 -o signmessage tb1qeh090ruc3cs5hry90tev4fsvrnegulw8xssdzx "asdasd" --testnet
Since then, the last one no longer works.
