Service Worker: Do not resurrect uninstalled workers.

Previously, service workers were resurrected when they were updated or when the same script was registered while the service worker was still alive. Now, registering a service worker will always create a new instance, regardless whether there already is a running instance or not. This spec change was intended to address the confusion that a service worker could become active again with no corresponding activate event.
