  When using realtime queues, app_queue wasn't updating the strategy if it was changed in the realtime backend.  This patch resolves the issue for almost all situations.  It is currently not supported to switch to the linear strategy via realtime since the ao2_container for members will have been set to have multiple buckets and therefore the members would be unordered.
  
  (closes issue #14034)
