Try to clone git repositories over SSH on failure (#671)

* updated help message for `now switch` to reference the argument for the team as the slug instead of the id

* try ssh if https does not work

* add editor settings to .gitignore, update yarn.lock

* reverting change to teams in separate pr

* Removed unused ignored prop

lib/git.js
