⚗️(service-worker) remove index from cache first strategy

Some users reported that the app was giving a
blank page, it seems to happens often after a
release. It could be due to the fact that
the service worker is caching the index.html
file and not updating it properly after a new release.
We remove the index from the cache first strategy
to avoid this kind of issue. We set as well
the default handler with the "StaleWhileRevalidate"
strategy to force the cache to be updated in
the background.
