[dns-operations] DNSSEC and ANY query

The first dig is what you want to see.
The latter shows something went wrong in the signing process.
Looking at yehoo.org./IN/ANY, there's no DNSKEY at the apex, as well
as no other records. I looked there to see if there was an
NSEC3PARAM or NSEC record, there was neither, so I couldn't tell if
NSEC was missing from dnssec-test.yehoo.org. (If you signed with
NSEC3, there'd be no NSEC3 record not NSEC record in the ANY reply.)
This tells me there's something wrong in the server too.
