Fix for queryCaa ENODATA when using local DNS

[DeBuXer]

Improved error handling when retrieving the CAA record. It sometimes failed when you requested a CAA record for a domain that did not have one. This issue did not occur with subdomains for a certain reason.

Thank you! Can you make it consistent like the other one? Maybe one line change would be enough

const records = await dns.resolveCaa(host).catch(() => null);

This is indeed a better approach. However, I had to use the nullish coalescing operator, otherwise, the error 'Cannot read properties of null (reading "filter")' would appear when no CAA record was found.
