[FIX]purchase_manual_delivery: uom fixes

Fixed issues when uom_id and uom_po_id of a product are different.
- Comparison for Purchase Order Line pending to receive now uses the product quantity that uses the uom of the Purchase Order Line.
- When creating the Stock Move the quantity is now computed into the uom of the Stock Move
