[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. lp bug: https://launchpad.net/bugs/507694 fixed bzr revid: odo@openerp.com-20100202213752-lffj73sbobyw6ygk
