[FIX] account: Fiscal position tax mapping to including tax

According to the documentation it makes sens to map an excluded tax
with an included tax. For example in Belgium, B2C taxes are generaly
included and B2B taxes are excluded. Then we can manage this situation
by creating a pricelist with prices for B2B and B2C.
