c37ecb7a - Check for `room` in all `Room.timeline*` handlers

Check for `room` in all `Room.timeline*` handlers All `Room.timeline*` handlers must currently test for `room` first if they expect it to exist. It is emitted not only for rooms, but also for timeline sets without rooms, such as for notifications. Almost all such handlers were correctly testing as needed, but it was missing from `RoomBreadcrumbs`. While that's quite confusing, we can start by testing for `room` when we expect to have one.
