Removing `isBlank` check
Removing `isBlank` check

When checking for `isBlank` while using `same` is leads to validating a field that is empty even when the field it's being validated against has data in it.

e.g: `password` and `confirmPassword`. `password` has `12345678` and `confirmPassword` is `null` and it will still validate it as correct.
