[FIX] l10n_ar: add missing translations

Issue: spanish_ar translation is missing for some menu items and template names in the accounting app

Steps to reproduce:
1- install l10n_ar
2- switch language to Spanish(AR)
3- Open accounting app
4- check menu items

Solution:
Issue was that the translation file was called es.po and for spanish (AR) language it should fallback to es_419
As per the translation code found here in in 'translate.py' in odoo tools
