Steps to reproduce the bug:

- Let's consider a company in $
- Let's consider two sales taxes T1 (10% included) and T2 (0%)
- Define a fiscal position FP that maps T1 to T2
- Define a product P with T1, price = 11$ and available in the shop
- Define a pricelist PL in € such as 1€ = 2$, show discount to customer and discount P with 50%
- Define a portal user PU with FP and PL
- Log with PU
- Add P in the cart

Bug:

The unit price of P was 2,75€ instead of 2,5€ and the discounted price was 10€ instead of 5€

PS: Before adding P in the cart, the correct unit price and discounted price were displayed.
