(maint) Route53 spec bug with zone ns record order

 - AWS doesn't always return resource_records for ns in the same order
   in which they were set.  Fortunately, the type code compares array
   entries as sets already, so no module code needs to change.  The test
   has recently been observed as failing, however.
