[FIX] l10n_ar: total invoice amount on printed invoice

Total amount on printed electronic invoice include taxes if the electronic invoice has argentinian vat and document type 'B', 'C', 'X', 'R'. Also if the invoice mentioned before have more than one tax and one of them is different than "IVA" (argentinian vat), then is necessary not to show in the printed invoice report the amount untaxed of the invoice.
