[FIX] l10n_latam_invoice_document: For the latam invoice reporte show the base property in the correct value and currency

The problem that occurs before of this commit, is due the base of the taxes is in the currency of the company not in the invoice currency. For that the value that shows in this cases for the base is not correponding for the symbol of the currency.
After this changes we show the correct value an symbol for the base converting the value when is necessary.
