Make TestAPIServingCertificateAutoCreationAndRotation more reliable.

Browse Source 
This test has occasionally flaked because it only waited for the APIService GET to finish, but did not wait for the controller to successfully update the target object.

The new code should be more patient and allow the controller up to 10s to perform the expected action.
