[FIX] account: avoid wrong taxes quick encoding

How to reproduce:
- Activate l10n_be and go on a Belgian Company
- Activate Quick Encoding on Bills
- Setup account 600000 with taxes 12% (Sales) and 12% M (Purchase)
- Create a Bill
- Put 112 as the amount Tax Incl.
=> Both taxes are put on the line, which makes no sense, resulting
a sale tax on a purchase document.
