Error message on invalid credentials

If customer on login page enters bad credentials localized error message is shown and validation control adds extra message "The credentials provided is incorrect." that is not localized. E.g. for Russian it looks:

Попытка входа не удалась. Исправьте ошибки и попробуйте снова.
The credentials provided is incorrect.

The decision is to change in CustomerController.cs on line 182:

ModelState.AddModelError("", "The credentials provided is incorrect.");
to
ModelState.AddModelError("", "");

Thanks for info
