fix(@angular-devkit/build-angular): ensure service worker hashes index HTML file for application builder

The generated HTML files for the application were previously not included in the hash calculations for
the service worker. This has now been corrected and the index file for an application will not be included
when service worker support is enabled via the `serviceWorker` option.
