Exit filter mode when a filter is typed and a room selected pressing Enter

[jcromero]

Is your suggestion related to a problem? Please describe.
It's very inconvenient to use the keyboard to select rooms. I can do Ctrl+K, filter the name of the room hitting some keys, and press Enter to select the first filtered one. But the filter remains active and I have to Ctrl+K again and press Backspace to show all the rooms.

Describe the solution you'd like
When pressing Enter to select the first match in filter mode, the mode should be exited.

Describe alternatives you've considered
No one.

Additional context
If no filter is entered in the inputtext field and I press Enter the behaviour is the one suggested, so there is an inconsistency here.
