Rewriting https queries with $dnsrewrite preserves the original cname result

### The problem

A query for https records for rr5---sn-q4fl6nlz.googlevideo.com normally returns a https record 和 a cname record. I then rewrote the https record using this rule
`||googlevideo.com^$dnstype=HTTPS,dnsrewrite=NOERROR;HTTPS;1 . alpn=h2`
When you query the domain again there are only https records.

### Proposed solution

When rewriting the HTTPS record, if there is a CNAME record, please keep it.
