Fix broken slot reuse when fetching alternates

When fetching alternates, http-fetch may reuse the slot to fetch non-http
alternates if http-alternates does not exist.  When doing so, it now needs
to update the slot's finished status so run_active_slot waits for the
non-http alternates request to finish.
