Input::prepareRequiredValidationFailureMessage return value

[metanav]

After upgrading to 2.5.5, Apigility validators are not showing expected error message for required fields if error_message is not set. Previously, it was showing the error message from a NotEmpty validator if present in the validator chain.
I think the newly introduced prepareRequiredValidationFailureMessage() method should return existing NotEmpty validator message, if present in the validator chain.
