[7.0][6.1][account_chart_update] Wrong dict passed in function to that leads to TypeError

I'm testing 6.1 but since this part of the code didn't change in 7.0, it should also happens in both versions.
The problem comes from "action_update_records", the wrong dict is passed in _update_accounts so tax_template_mapping = taxes_res['pending']. That's wrong, it should be taxes_res['mapping']

        accounts_res = self._update_accounts(
            cr, uid, wizard, log, taxes_res['pending'], context=context)

        accounts_res = self._update_accounts(
            cr, uid, wizard, log, taxes_res['mapping'], context=context)

For the record:
