   ### What problem does this PR solve?
   
   Issue Number: DORIS-23587
   
   Related PR: None
   
   Problem Summary:
   
   `test_join5` creates the `uqv1` view on top of `uq1`, but drops `uq1` while 
the view still exists. A concurrent `information_schema.view_dependency` scan 
can observe this dangling view and fail while resolving its missing base table.
   
   This change drops `uqv1` after its last assertion and before dropping its 
base tables, so the case does not expose an invalid intermediate state to 
concurrently running regression suites.
