Because of incorrect BPR in LPS-71245 the issue is still reproducible in 7.0.x

Steps to Reproduce:

1. Create a new form with:
   1. A text field with label Correo Electrónico (CorreoElectrónico will be the field name).
   2. Add to the text field a validation (email type) with any error message.
2. Save the created form.
3. Edit again the email field and check validation.

Expected Result:
Validation type is saved and applied to form values entered.

Actual Results:
Validation doesn't appear to be saved, but when filling a form error message always appears even if mail is valid.
