Is there case with EMPTY subdirectory also covered (that it does not prevent schema from being deleted)?

I've changed that behavior so empty directories won't be deleted, and I added a test for that as well.

These lines aren't actually changed; I just switched the order of this test and the next after renaming them, and they're so similar that git didn't realize.

Previously, files in subdirectories weren't considered when deciding whether to delete Hive and Iceberg schema locations when the schema was dropped.

This fixes an error in #10146 and #9767 that caused files in subdirectories to be ignored when determining whether to delete schema locations when dropping Hive and Iceberg schemas.
(Any empty subdirectories will still be deleted with the schema, though.)
