ShipmentScheduleBL.updateSchedules fails after C_Order was voided

Testcase to check if shipment schedules are deleted correctly after a sales order is voided.

1. Create and complete a sales order for G000X:
   • P0001, 5 TU A
   • P0002, 3 TU B

2. Create the inout from shipment schedules (leave the window open!)

3. In the shipment, set the qty for P0001 to 3 TU A, to create a partial inout, complete

4. In shipment schedule window, refresh:
   • => P0001: qty to deliver: qty of 2 TUs, orange
   • => P0002: qty to deliver: 0, red

5. Go back to you sales order, and void it

6. Check the console:
   • => no errors regarding “update or delete on table “m_shipmentschedule”” or exceptions like “Found QtyPicked record with non-zero qty even if the shipment schedule has QtyDelivered=0”
7. Check your shipment:
   • => shipment is deacitvated, docstatus is Nichts
8. Check your shipment schedules again:
   • => the shipment schedule for P0001, with the partial inout, was deleted
   • => the shipment schedule for P0002, that was fully delivered, has all qties=0, is read-only and processed
   • => tab for shipment of shipment schedule for P0002 shows inout as deactivated
