fix(Tryton): restore send sales test and fix TrytonSale.build_tryton_comment

- Restored test_exportar_ventas_para_tryton.py with full parameter
  validation for client.call (method, context, sale fields, lines)
- Fixed TrytonSale.build_tryton_comment referencing self.catalog_sale
  (nonexistent) instead of self.sale.description
