ServiceWorker: Early reject error if url is something wrong.

 // This helper will setup a small test framework that will use TESTS and run
 // them sequentially and call self.postMessage('quit') when done.
 // This helper also exposes |client|, |postMessage()|, |runNextTestOrQuit()|,
 // |synthesizeNotificationClick()| and |initialize()|.
