dialog: release of dialog for not-forwarded initial request done by creator
- avoid releasing new dialog in case of upstream paralel forking or retransmission by other processes than the other which created the dialog - it could result in destroying the dialog in initial state if the request was not forwarded yet, likely to happen because creator process runs more callbacks
