Subject: [PATCH] fix pwa installability by adding fetch event listener to
 noopServiceWorker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

currently google chrome prevents installing pwa due to the error: “Page does not work offline”. The reason is service worker has to listen to fetch event. It doesnt have to do anything so the listener can be an empty function, but it has to be declared
