Bug 1180754 - Get serviceworkerobject-scripturl test passing. r=bkelly

This commit does several things:
1. Change to https so the test does not fail due to security exceptions.
2. Change function service_worker_unregister to get around the "getRegistration() matches most specific registration" issue by matching exact scope.
3. Uses the URL object for the "absolute" test instead of relying on server substitution since it achieves the same thing.
4. Allows fragments in the scriptURL since I cannot find anything in the spec preventing this. I have filed https://github.com/slightlyoff/ServiceWorker/issues/742 to resolve this.
