> Current logic does not handle orphaned auto created child queues. The following example steps show a scenario in which it is possible to submit applications to an orphaned queue, that has an invalid (already removed) ParentQueue.
> # Auto create a queue root.a.a-auto
> # Remove root.a from the config
> # Reinitialize CS without restarting it (possible via mutation API)
> # Submit application to root.a.a-auto, while root.a is a non-existent queue
