A patch from Christian Carlow for "Shipment cancellation doesn't revert inventory accounting quantity total" https://issues.apache.org/jira/browse/OFBIZ-5314

When order items are issued to a shipment, the accounting_quantity_total
for the corresponding inventory records are updated but afterwards when
the shipment is cancelled, the accounting_quantity_total is not reverted
back to the original values.  Is this a bug or is there a reason the
quantity is not reverted?

The problem is that when I try to create another shipment and issue the
same quantity, I receive the following error:

The following error occurs when I try to issue the same previously
cancelled quantity to a newly created shipment:

Error:<br/> ERROR: Could not complete the Issue OrderItemShipGrpInvRes

The service is looking for inventory_item records with an
accounting_quantity_total > 0 but finds none because the quantity was
decremented to 0 from the cancelled shipment issuance.
