It turns out that the real (not mocked) implementation of JobTicket creation is already required now for this planned (mock)Dispatcher setup; moreover, this real implementation turns out to be almost identical to the mock implementation written recently -- just nested structure of prerequiste JobTickets need to be changed into a similar structur of ExitNodes -- as an aside: rearrange various tests to be more in-line with the envisioned architecture of playback and engine
