Add new transaction starting -> error on timeout
Exception along the `starting` inspection code may causes `no defined transition` error as there is no transition for `starting` state on timeout event. Also it could happen if small timeout configured, so there is not enough time for starting -> waiting transition, e.g. new greenthread spawn is blocked due to missing of available slots. Closes-Bug: #1662494 Change-Id: I66cf0374a2ba4ab4692110daafd4a3d2d20d56d6
