Revert of Revert of ServiceWorker: Remove Clients.getAll()

LayoutTests/http/tests/serviceworker/chromium/resources/notificationclick-can-focus.js

 // 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()|.
