This is pretty important since initiating will reset the cache.
If we don't do this, it's possible to have old cached resources
after the user decided to remove all of the prefetching logic.
In this case, even the page didn't prefetch it'll use the
previously cached pages. That because of there might be a already running
service worker.

* Move prefetcher code to the client from pages
Now we also do a webpack build for the prefetcher code.

We also clean the cache always, even we initialize
the service worker or not.
