Messages on the private bus have no sender. As it is now, when a job is canceled through it, as "systemctl cancel" does when run as root, we pass a NULL name to sd_bus_track_contains(), which fails an assert_return(). In developer builds, that makes PID 1 abort. Otherwise it's only logged at debug level, and we consult polkit, as we should. Let's only check whether the sender owns the job for messages on the API bus. That's the only bus bus_job_track_sender() tracks senders on, so jobs enqueued through the private bus aren't tracked anyway. (cherry picked from commit bfeac4c30e1a818cda14c8d1b347d500a9dfe4e3)
