When Nexus is upgraded to 3.22 and the fix implemented within
NEXUS-22770 kicks in, the existing assets are deleted and a rebuild of the browse nodes is also run.
However, it seems that the rebuild is run in parallel with the delete and may not find any nodes to delete as they have not yet been deleted.
This means that the browse node tree is broken until a subsequent rebuild is run.
Expected: The rebuild should not be run until the deletion has taken place.
