Delete an incorrect and also redundant translation file in account_chart_wiz_dates module.
Created by: zaoral
The module account_chart_wiz_dates have an unnecessary i18n/en.po file. The en.po file should be a a english translation but is really a translation to spanish. The use of this file is incorrect and also redundant because the pot file figure as the english transtalation. Please delete this file.
Also need to update the es.po file. I check between en.po and es.po file and some translate terms from en.po can be move to es.po.
