resolved: match CNAME replies to right question
Previously by mistake we'd always match every single reply we get in a CNAME chain to the original question from the stub client. That's broken, we need to test it against the CNAME query we are currently looking at. The effect of this incorrect matching was that we'd assign the RRs to the wrong section since we'd assume they'd be auxiliary answers instead of primary answers. Fixes: #18972
