Use self.run_run instead of self.run_run_plus

Using a salt.runner.Runner() instance to run this test has exposed a
problem with run_run_plus, where the fileclient doesn't behave as
expected. Since the raw return data is not needed, using run_run here
lets the test pass while we continue to work on run_run_plus.
