[FIX] repair: reserve parts

- Create some stock in WH/Stock for product A
- Create some stock in WH/Stock/Shelf 1 for product B
- Create a Repair Order for Product A in WH/Stock
- Add a line in Parts with B, leave the location to WH/Stock
- Process the order until the end

Negative quant is created in WH/Stock for B instead of using the
quantity in WH/Stock/Shelf 1.

We do a best effort in order to reserve the quantity in the
sub-locations.
