[FIX] stock: immediate transfer w/ tracked product

How to reproduce:
- Create a tracked product;
- In the receipt picking type form view, for the lot and serial numbers,
  uncheck "Create New" and "Use Existing ones";
- Create a planned receipt for some of this tracked product;
- Confirm and validate the receipt:
  It opens the "Immediate Transfer" wizard;
- Apply the immediate transfer:
  -> It asks if you want to create a backorder.

Since the picking type doesn't use new or existing LN/SN, it accepts to
be confirmed even if some move lines for tracked product have no
tracking numbers.
The issue was, when a `stock.move` sets its done quantity to its
reserved quantity, if its product is tracked, it doesn't change its done
quantity if it has no tracking number, regardless the picking type's
configuration.
