Some qualifiers probably cannot be removed

- wikibase-cli version: latest
- OS version: Win 11

The "remove-qualifier" relies on qualifier hashes. However, it seems that not all kinds of qualifiers have value nodes (see https://www.wikidata.org/w/index.php?title=Wikidata%3ARequest_a_query&diff=1913209343&oldid=1913178332 ) . So, it is currently impossible to remove these with Wikibase-CLI.
