This is inherently flaky - there is no guarantee that js will have injected in 2
seconds.

Instead, we should cause a visible change to the page (e.g. setting a variable
on window, modifying the title, etc), wait for a deterministic point after which
we know the content script would have injected, and then check it.

This case is already tested under a different test, removed it.

+setTimeout(function() {
+  chrome.test.notifyPass();
+}, 2000);

<random comment spot because I can't comment in inject.html> looks like
inject.html is empty?

Yes, I just needed a valid page to browse to so code could be injected. This
test was removed however.
