Remove hba-only directories in clear_existing()remove-hba-dirs

rtslib never creates hba directories without a storage object within it,
but if under some circumstance these existed then clear_existing() wouldn't
remove them, since StorageObject::all()'s glob ignores them.

Add code to ensure these are also removed.
