ESC causes unwanted closing of the join/create community view

[kingalg]

Version: spotted on 6.3.0, but it's probably an old issue that we missed earlier. System: all desktops

Issue: When the user is in the join/create community view and presses the "Esc" button, first the Quiet logo appears, and then (after pressing Esc a second time), a white screen appears. To go back to the correct view, the user must restart the app. Below, you can see a recording where I press the Esc key twice.

I checked this on all available to me systems (Windows, MacOs and Linux Ubuntu) and it seems to be a problem on all of them.
