[FIX] Properly cancel a draft purchase.order when unlinking it, so correct workflow signals can be propagated to parent workflows if there are any. 

Note: in trunk a different mechanism should be added to automatically propagate e.g. a subflow.delete signal whenever a record with a parent workflow is unlinked. This would allow adding an explicit transition from the subflow node in the parent flow for these kind of cases.
