[Prep work for #70443650] Fix broken integration tests

During work on [#70443650] it was discovered that the integration tests were not functioning due to the 'expect(false) == true' bug seen elsewhere.

This PR fixes this up, and corrects the resulting failing tests.

When Vcloud::Core is updated to use get_network_complete (which will cause vcloud_attributes to return different data), these tests will need to be refreshed.
