[workflow] finish refactoring introduced by 021035b9a7ab for 'go back' transition:
* fix SubWorkflowTransition.destination() prototype (must now take an entity as argument)
* fix the change state for to give the entity to the transition's destination() method
* we need a new method to draw workflow since we've no entity to give and 'go back'
transition usually go back to multiple states
