Remove the queued states mechanism from ServiceWorker

Remove the queued states mechanism from ServiceWorker

It can instead be handled by WebServiceWorkerImpl for better clarity
about who is the source of truth. That will happen in a subsequent
Chromium patch: https://codereview.chromium.org/255813003/

This patch is a follow-up to Blink r172459:
https://codereview.chromium.org/247263010

[falken, 2014-04-25 07:45:19]
