Small cleanup in db.sqlalchemy.api.action_finish()

This function was pulling back a row, updating the returned object,
then returning a reference to it. This potentially races, as the
object may be updated in another transaction after fetching. In
practise it's probably fine, but the new code is more obviously
correct, and probably slightly nicer to sqlalchemy.
