    serverRoomManager: Handle already joined rooms
    
    It doesn't make sense to allow users to select already joined rooms,
    or to leave rooms by unchecking them. On the other hand, hiding rooms
    that clearly exist would be weird as well, so represent joined rooms
    as checked but insensitive.
