ci: stop the release smoke test at the chat list, require the directory row on the branch

Run 38712854507 showed that the released app (v7.1.0-beta.6) has no search field after onboarding: with no chats its left pane is empty and the centre shows "Talk to someone", while the branch shows the search bar in that state. The chat list is now recognised by "Talk to someone", which both show; the release job stops there (onboarding mode), and the branch run again requires the "Search in Directory" row after typing.
