[ServiceWorker] Tests for Clients.openWindow().

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