[ServiceWorker] Revise wpt tests for Client.type

 // This worker is designed to expose information about clients that is only available from Service Worker contexts.
 //
 // In the case of the `onfetch` handler, it provides the `clientId` property of
 // the `event` object. In the case of the `onmessage` handler, it provides the
 // Client instance attributes of the requested clients.

     e.respondWith(Response.error(
       '`clientId` incorrectly set to non-null value for request with mode `navigate`'
