Fix Materialentnahme movement creation

Testcase to check if the correct movements are created for Materialentnahme.

1. Create a purchase order for G000X:
   • P0001, on 3 TU A
   • P0002, on 5 TU B
2. In Wareneingang POS, create different receipts (note the destination warehouse and the HU values!):
   • P0001: 1 TU A on 1 LU
   • P0001: 2 TU A on 1 LU
   • P0002: 2 TU B on 1 LU (use split & join to have a free TU as well)
   • P0002: 3 TU B on 2 LU (split off 1 or 2 TUs on a new LU)

3. Open Handling Unit POS, and your destination warehouse

4. For each material receipt, select the HUs (select both LUs from 4th receipt!!) and click Materialentnahme:
   • => movement is created (note the doc no.)
5. Open Warenbewegung, search for your movements and check the lines in the 2nd tab (qties!):
   • => 1st movement: 3 lines, 1 LU, 1 TU, and x CU (qty of product)
   • => 2nd movement: 3 lines, 1 LU, 2 TU, and x CU (qty of product)
   • => 3rd movement: 3 lines, 1 LU, 2 TU, and x CU (qty of product) (no difference between 2 aggregated TUs and free TUs!)
   • => 4th movement: 3 lines, 2 LU, 3 TU, and x CU (qty of product) (no difference between 2 aggregated TUs and free TUs!)
