Lucas Perais (lpe) 59c663ae42 [FIX] point_of_sale: correct compute fixed tax negative quantity
Have a product with a fixed amount tax.
Make a "return" of that product in the pos (i.e. negative quantity)

Before this commit:
- The amount of the return was `tax_amount + product_amount` instead of `-1 * positive_total_amount`
- The amount differed from what can be observed in sales

This was because the sign of the quantity was applied twice

After this commit,:
- the amounts of positive and negative amounts are symmetrical
- they match the behavior in sale

The logic is very similar to bb72dea98d
