<rdar://problem/43431632>
Reverted r234991 for reason: Caused an assertion failure on the bots. Committed r235001: <https://trac.webkit.org/changeset/235001>
imported/w3c/web-platform-tests/service-workers/service-worker/windowclient-navigate.https.html would sometimes fail the MESSAGE_CHECK(frame) in WebPageProxy::didReceiveAuthenticationChallengeProxy because sometimes the frame wouldn't exist in the UI process yet. We really need to get rid of API::LoaderClient because we shouldn't even need the frame to exist.
r235398 removed that message check. This is now valid. Will reland.
