Do not cache NS from referral in negative responses

Stop storing the NS referral into the main cache when processing a
negative response.  These records are already cached in the delegation
database and are not needed elsewhere.

Update dnssec tests that relied on parent-side NS RRsets being
returned in recursive query responses.
