Original change's description:
> service worker: Add WPT tests for resultingClientId.
> 
> This adds a ?client variant to navigation-redirect.https.html, which
> does a lot of redirect tests. This tests the following:
> - resultingClientId is the id of the client, if one was created via
>   that request.
> - get(resultingClientId) for requests that did not create a client
>   resolves with undefined.
> - resultingClientId is reset on cross-origin redirects.
> - Client.url is the creation URL.
