#298 ShipmentSchedule updating fails on missing UOM conversion

Testcase to check if the shipment schedules update correctly if a UOM conversion is missing.

1. Open Product window, search for P0001

2. Check the UOM, make sure a UOM conversion exists:
   • UOM: e.g. PCE
   • UOM conversion: 0.01 / 10 for PCE / Kg

3. Open pricelist CP, search for P0001

4. Make sure the price UOM is different from the product UOM (or set it differently for testing!)
   • e.g. Price UOM: Kg
   • Price 3.00 EUR per Kg
5. Create a sales order for G000X, for P0001, for 10 PCE
   • => orderline for 10 PCE P0001
   • => product UOM: PCE, price UOM: Kg
   • => price: 3.00 (10 PCE = 1 Kg)
6. Zoom into the shipment schedule, when it’s created
   • => Maßeinheit: PCE
   • => Netto (offen): 3.00

7. Go back to Product, UOM Conversion, and deactivate the conversion

8. In Lieferdispo, refresh (change sth like e.g. Prio, and save, so refreshing is necessary)
   • => Netto (offen) is now set to -1.00, because of the missing conversion
9. Create the inout with Auswahl liefern
   • => inout is created without errors, despite Netto (offen) was changed and the UOM conversion is missing
