Description

The old auto queue creation/managed queue logic allowed the definition of childless parents to be created statically, if the auto-create-child-queue flag was turned on the parent (thus making it a ManagedParentQueue).

Since it is not an edge case, we also need to support the creation of a ParentQueue instead of a LeafQueue, if auto-queue-creation-v2 is enabled, even when no child queue is defined under the parent.
