erp5_interaction_drop: Don't patch accounting_workflow transition for guard

   This patch would replace guard for deliver_action to not call isDivergent that would make slow when open a Transaction (I don't remember the reason exactly, probably due large simulation trees).

   This breaks guards when simulation is not used (so it will never be solved) since the transition would never be allowed to the accountant.

   So if isDivergent proves itself slow, we should patch differently, for now keep the original implementation, since it is proven to work.
