Fixed TestWithLooperRule switch for UiThreadStatement and ExpectException

When switching from AndroidTestRunner to AndroidJUnit4, the annotation @Test(expected = <Exception> wrap the test method, which is delegated out to AndroidTestRunner if it's there, but a switch statement in wrapMethodInStatement is called in the AndroidJUnit4 case, which caused an exception for the uhandled case.
