Since you're presenting in this test, probably good to assert that a VR display
is found like in other WebVR tests.

I think tests should be as simple as possible. Another test is already covering
the check that a VR display is found, so we don't need to check that again here.

+        enterVrTapAndWait(mWebContents);
+        waitOnJavaScriptStep(mWebContents);
+        endTest(mWebContents);
