* Fix reference counting used in the __queues_show function
* Add code to be sure that the "queue show" command does not
  print information for a realtime queue which has been deleted
  from the backend
* Add a missing unref to the realtime queue loading function for
  the case where a queue is in the module's container but has been
  deleted from the realtime backend
