[FIX] l10n_es: fix base tags for groups of taxes

Before that, groups of taxes defined in l10n_es only defined tags on child taxes. This is wrong: base tags of a group of taxes should always be set on the group itself; children should only contain tax tags (at least, if their type_tax_use is 'none'). Indeed, the tax_ids field of aml generated for these taxes will point to the group, while tax_line_id points to its children.
