Bug 1567378 [wpt PR 17920] - Update rejects_if_not_active.https.html, a=testonly

Automatic update from web-platform-tests
Update rejects_if_not_active.https.html (#17920)

Use a second payment sheet to detect that the first payment sheet is dismissed as a result of navigation instead of relying on the rejection of the first promise, which may never settle in some implementations (i.e. Blink).
