Non-activity translation (#1434)

- When in activity, allow translation using other non-activity schema if
we get an unknown action with activity schemas.
- Activity can set "restricted" to disallow using non-activity schemas.
- Make sure the activity state are not used in the prompt for
non-activity schemas.
