No validation message - digits in city field

[ArturDivante]

Related issue:

#2653

Steps to reproduce the issue

1. Place some items in cart and go to checkout
2. Fill required fields
3. Input ONLY numbers (i.e. '001') in City* field

Current behavior

Frontend checks, if there is at least one letter in the field. So for example '123a' will be acceptable. But if there are only digits in the field, proceed buttons ('continue to payment' and 'go to review order') become inactive/grayed. However, no validation message is displayed, so user have no idea, why he cannot proceed. He may not even be aware that he made a mistake somewhere in the form.

Expected behavior

Front behaviour should reflect backend validation. If input is unacceptable (like in this case) - proper validation message should appear.
