Subject: [PATCH] [FIX] sale: recompute tax amount after fiscal position change

When changing the fiscal position of a sale.order, the taxes are recomputed
which means that total amounts may no longer be correct (need to press 'update'
button).
Reset the amount_* fields to force the recomputation at write.
