* Tests for RoomNotificationStateStore emitting events
* Support dynamic room predecessors in RoomNotificationStateStore
* Remove unused arguments from emit call.
UPDATE_STATUS_INDICATOR is used in:
* SpacePanel
* MatrixChat
* RoomHeaderButtons
but these arguments are not used in any of those places. Remove them so
when I refactor I don't have to make up values for them.
* Fix broken test (wrong expected args to emit)

* Update the RoomNotificationStore whenever the predecessor labs flag changes
* Fix type errors
* Fix other tests that trigger our new watcher
