test(web-shell): reach the owning conversation before retrying a foreign pending

A pending prompt owned by another conversation no longer offers retry in the
foreign session: it renders "Open the original conversation" instead. The
spec still clicked "Retry the same request" straight from the foreign session,
so the two foreign variants timed out waiting for a button that is deliberately
absent from this head while the owner variant passed.

Follow the redirect first, then retry. Owner variant unchanged.
