Heal the namespaceless ingresses in federation e2e.
For createIngressOrFail, it incorrectly returned the ingress passed in as an argument, which does not include the namespace, instead of the ingress returned from the create call (which does).
This in turn leads to errors in e2e tests like this:
INFO: Waiting for Ingress federated-ingress to acquire IP, error an empty namespace may not be set when a resource name is provided.
