/**
* A simple, no-op service worker that takes immediate control.
* Use this file if the active service worker has a bug and we
* want to deactivate the worker on client browsers while we
* investigate the problem.
*
* To activate this service worker file, rename it to `worker-basic.min.js`
* and deploy to the hosting. When the original worker files cache
* expires, this one will take its place. (Browsers ensure that the expiry
* time is never longer than 24 hours, but the default expiry time on Firebase
* is 60 mins).
