Rui Matos 2f228e21da status/keyboard: Backup the whole MRU list while in password mode
Instead of saving only the current input source when entering password
mode, let's save the whole MRU list so that we can restore it when
returning to normal mode.

This is closer to user expectations since password mode is a transient
and short lived state.
