Fix mypy: now it catches this error thanks to the ProvidesUserContext type hint

            if user_details:

                stmt = stmt.outerjoin(Job.user)

        else:

            if history_id is None and invocation_id is None and implicit_collection_jobs_id is None:

            if history_id is None and invocation_id is None and implicit_collection_jobs_id is None and trans.user:

                stmt = stmt.where(Job.user_id == trans.user.id)

            # caller better check security
