Fixes outstanding failing tests

Fixes three failing tests.
For test_ipinfo_ResolutionFail it fixes the following issues:
* failing when no network is available
* failing when Google changes the ip addresses of the service
* failing when the order of returned ip addresses is different
For test_DeleteRecordInitial_Empty and test_DeleteRecordInitial it fixes a not
existing BindServer object.
