fix: usr: The resolver now removes other RRsets at the same name when caching a CNAME

When an RRset is in stale cache, and the authoritative server changes the record type to CNAME, the resolver fails to refresh the stale cache. This has been fixed.

Closes #5302

Merge branch '5302-serve-stale-cname-to-a' into 'main'
