Skip the validation for integer type with empty values.

[Malith-19]

Purpose

• $subject

Related issues

• The failedLoginAttempts attribute throws a NumberFormatException if present in the User Profile when saving. product-is#22281

Approach

• With this PR, we are skipping the validations for integers when we recieve a empty string("") that means users can clear the integer value.
• At the moment if we receive a empty string then it will give 500 error when it tries to decode.
• With this fix, it will skip the value pass point and validation point for integer type when value equals to "".
• Note: When we set the value to "" in attribute this will not return to FE and therefore behaviour will not change as previous.
