Add createHandlerBoundToURL response to the cache if it is missing

Library Affected: workbox-precaching

Browser & Platform: “all browsers”.

Issue or Feature Request Description: We use to code to precache navigation route “app-shell.html” as

const handler = createHandlerBoundToURL('/app-shell.html');
const navigationRoute = new NavigationRoute(handler);
registerRoute(navigationRoute);

but if the item, for some reasons and with someone (buggy code, extension or by user), is deleted from the cache - we have not have offline mode in the future requests will be made to the server but the result will not be stored in the cache

Please add an ability to put the response in the cache if it’s absent in it in createHandlerBoundToURL code

the same problem occurs with precacheAndRoute when deleting the entire cache the application will work online but will never work offline
