Fix the xgboost_synthetic test so it actually runs and produces signal

* The test wasn't actually running because we were passing arguments that
  were unknown to pytest

* Remove the old role.yaml; we don't use it anymore

* Wait for the Job to finish and properly report status; kubeflow/testing#514
  contains the new routine

* The test still isn't passing because of kubeflow#673

* In addition we need to fix the auto deployments kubeflow/testing#444

Related to kubeflow#665
