FLX-2302: journey transition is not in the taxonomy

Family: plan/replay binding (the 2000 band)

A Journey's personaReactions[].nextState is not a state of the referenced JourneyTaxonomy, or the edge from the subject's current state to it is not one of the taxonomy's transitions. The offline validator checks the state's membership; the engine additionally checks the edge, because a legal state reached by an illegal edge would put a transition in the run digest that the taxonomy forbids.
