WPT: service worker: Fix potential race in navigation-redirect.https.html.

Before this CL, the test makes a frame which posts a message to the test
window. But if the test fails, we might not consume the message with
`await` and move on the next test. It's possible the next test gets an
unexpected message from the previous test.

I think a related issue caused the timeout after the Clients variant was
added to the test, since the message handler was created after the frame
was created and it was possible the message arrived after that.

Fix things by explicitly asking the frame for the message when we're
ready for it.
