This is a follow-up story for
MODORDERS-94 to refactor "create Instance Record in inventory" logic, namely:
, PUT is performed by deleting the whole Order (including PO lines) and creating a new one. So "create Instance Record in inventory" logic that is currently called when PO line is created, will be triggered when PO status is changed from Pending to Open
PUT Orders is updated to not re-create PO lines, we need to make sure that "create Instance Record in inventory" is triggered for all previously created PO lines when Order is moved from Pending to Open status.
