The same dns::record should be used during rollback
|Assigned to:||Paul Kelly||% Done:||
During rollback an attempt is made to create a new DNS::Record. This will always fail as the dns? test checks for errors, and yes, there are going to be errors, otherwise we would not be in rollback.
fixes #1386 - resuse dns::record during rollback
