test(ui): fix the Home answers in the stale pin spec

The spec asserts that the page shows no alert. The Home page raises its
own alert when the model list fails or a staging operation has failed,
and both answers come from the shared test server. A slow reply or a
failed install left there counted as an alert about the pin.

The spec now fixes both answers, so the alert count tells only about the
pin. The assertions are unchanged.
