kskroll-sentinel results are incorrect for is-ta

Summary

In the kskroll-sentinel code, the is-ta result comes back NXDOMAIN instead of NOERROR.

(This is marked as confidential because I don't want people to think that I'm ragging on folks who are implementing kskroll-sentinel; that could get in the way of adoption.)

Steps to reproduce

  1. Set up an authoritative server with the right kskroll-sentinel records. My running example is below.
  2. Create BIND (in this case, from the git repo in the 'v9_12' branch)
  3. Configure it trivially. My running example is below.

What is the current bug behavior?

# dig @bind-on-234.proper.com root-key-sentinel-is-ta-20326.this-is-signed.com
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 35304
;; AUTHORITY SECTION:
this-is-signed.com.	29	IN	SOA	q.com. phoffman.proper.com. 2018052100 300 60 1209600 300

What is the expected correct behavior?

You should get a NOERROR with the A record
