// The lifetime of the ServiceWorkerMainResourceHandle:
//   1) We create a ServiceWorkerMainResourceHandle without populating the
//   member service worker client.
//
//   2) If we pre-create a ServiceWorkerClient for this navigation, it
//   is passed to `set_service_worker_client()`.
//
//   3) When the navigation is ready to commit, the NavigationRequest will
//   call ScopedServiceWorkerClient::CommitResponse() to
//     - complete the initialization for the ServiceWorkerClient.
//     - take out the container info to be sent as part of navigation commit
//       IPC.
//
//   4) When the navigation finishes, the ServiceWorkerMainResourceHandle is
//   destroyed. The destructor of the ServiceWorkerMainResourceHandle destroys
//   the ScopedServiceWorkerClient which in turn leads to the destruction of an
//   unclaimed ServiceWorkerClient.
