Make navigator.serviceWorker.ready resolve with the controller. 

The specification for ready is here:
https://github.com/slightlyoff/ServiceWorker/issues/223

ready is a convenience that lets the page talk to an installed
ServiceWorker, without having to track the details of whether that
Service Worker is controlling the page, or merely installed but
waiting for the page to reload.

This implements the trivial ready case, where the page is
controlled by a Service Worker and ready can produce that one
immediately.
