ServiceWorker: Add LayoutTest for WindowClient.navigate().

LayoutTests/http/tests/serviceworker/chromium/resources/windowclient-navigate.js

+// them sequentially and call self.postMessage('quit') when done.
+// This helper also exposes |client|, |postMessage()|, |runNextTestOrQuit()|,
+// |synthesizeNotificationClick()| and |initialize()|.

|client| ("/serviceworker/chromium/resources/blank.html") seems to be
controlled.

Done.

According to the spec, non-controlled clients should not be navigated:

"4. If the context object's associated service worker client's active worker is
not the incumbent settings object's global object's service worker, return a
promise rejected with a TypeError."

[zino, 2015/09/22 07:53:31]

Done.
