Open the room live when tapping the notification for its newest message

Tapping a message notification always opened the room on a timeline
focussed on that event, even when it was the newest message and the
live timeline already ends with it.

On tap, the notification manager now checks whether any other delivered
notification for the same room is more recent. If none is, the room is
opened live instead of focussed. Older notifications in a room keep
focussing on their event.
