[FIX] purchase_stock: precision difference

- Create stockable product P: FIFO, Automated Valuation
- Set the price difference account
- Configure Decimal Accuracy for Product Price to 6 digits
- Create a PO
- Add a line with:
  Product P
  Quantity: 100,000
  Price unit: 0.005
- Confirm the PO, receive the product and create the invoice
- Set a price unit of 0.006 on the invoice line
- Post the invoice

No price difference booking is generated, while a price difference of
100 should be created.

It happens because we compare the price units with the currency
precision.

Comparing the price units, even with the proper Product Price precision,
is not a good idea. Indeed, in case discounts are applied the price
unit computed ends up with a larger precision.

As a solution, we check if the subtotal of the journal entry is
different from zero.
