Description

This PR fixes an issue where the app crashes when the user tries to change their selected video device when their camera is off. Now the user can change video devices while their video is off. This works before you join a room, and while you are in a room.

This PR also fixes the alignment of the settings menu that you see in the gif here.

Closes #389
