  Fix bug where final queue member would not be removed from memory.
  
  If a static queue had realtime members, then there could be a potential
  for those realtime members not to be properly deleted from memory.
  
  If the queue's members were loaded from realtime and then all the
  members were deleted from the backend, then the queue would still
  think these members existed. The reason was that there was a short-
  circuit in code such that if there were no members found in the
  backend, then the queue would not be updated to reflect this.
  
  Note that this only affected static queues with realtime members.
  Realtime queues with realtime members were unaffected by this issue.
