Complain about missing resources for compiled-mode PWA
Complain about missing resources for compiled-mode PWA

If the demo app is running in compiled mode, the PWA service worker
will now complain about any local resources that are requested by the
app but not marked for caching.  This helps catch missing resources in
the service worker's resource lists.
