Do we really need this step at all?

Well, we don't need the getConfig() (so I'm removing), but as the comment below
mentions, we do need this initial notifyPass() just to get the tests started.
This is a pattern that I've seen in a number of other tests.

But why do we need this instead of just, say, LoadExtension()?  That should load
the extension, and even wait for associated views to load.

Because I'm ignorant and don't understand how extension testing works ;-) I've
changed it to just use load extension.

+  // On first call, just pass so the test can continue. The real checks are in
+  // the content script.
+  chrome.test.notifyPass();
+});
