Fix room id parsing from notification tags

Thread notification tags have the form "roomId|threadId". clearReadRoomsNotifications
was building a RoomId from the whole tag, which is only validated in debug builds, so
in release an invalid room id reached RoomListService.room(). Add
NotificationCreator.getMessageNotificationRoomId(), the inverse of messageTag(), which
only keeps the part before '|' and checks it is a valid room id.

Also make RoomListServiceInterface.roomOrNull take a RoomId instead of a String.
