Reparent all jobs to their connections

(Mostly) fixes #397. Fixes #398. If there's a need to reparent the job
to some other object, it should now be done after callApi()/run() call
(not that there were many touch points before that moment, anyway).
Collateral damage: job-starting methods are no more const (but that
didn't belong them anyway, too).
