Fix a possible `list index out of range` when no answer is returned in the `ttl_changed` method
by applying the existing workaround for NS records to all record types.
Resolves#836

The SOA record for an existing zone is returned as an answer RR and not
as an authority RR. It can be returned as an authority RR for subdomains
of a zone.
