[FIX] stock: reverse picking in several steps

- Activate the receipt in two steps on the warehouse
- Create a PO for a stockable product
- Receive the product in Input zone
- Receive the product in Stock
- Reverse the move to Stock > products are back in Input
- Reverse the move to Input

You can't reserve quantities for this last move (from Input to Vendor).

This is because a picking has been automatically created from the Input
to Stock.

Original move which is reversed: Input -> Stock
When we reverse it, we don't want to send it back to Stock, so we need
to check the destination location of the original move, not its
location.
