TESTING: Clean-up records after TestDualProviders

[fabienmazieres]

Clean-up NS records after TestDualProviders, it used to leave ns1.example.com and ns2.example.com behind

@tlimoncelli ,
This bugged me a little bit, the testing suite removed all records except those 2 NS added during TestDualProviders
This little change should leave a perfectly empty zone :)

with a shortened test suite:
