bind 9.8.0 BUG dlz zone transfer

[Dan]

Tested bind 9.4, 9.6, 9.7 and 9.8, 9.8 is only version giving this problem.

The issue is when initiating a, bind only slave, to slave off of a,
dlz/mysql+bind master, debug logs show:
"refresh: non-authoritative answer from master"

I had set debugging on slave and master all night long on all versions of bind, 
and queries seem fine on 9.8, I can tell for certain queries are executing 
perfect like the previous versions and returning responses as they should, so I 
have ruled out mysql, there must be a bug within the 9.8 source tree doing this 
not updating aa SOA bit.
