Skip hidden field from validation

[maimoonak]

Fixes #1579

Description
Hidden field does not qualify for any validation. Response validation marks hidden field as valid and passes validation irrespective of it value

Alternative(s) considered
The validation skips the hidden field in when doing questionnaire-reponse validation. The other option could have doing it inside each and every validator but that makes it repetitive, non central, and does not keep room to revert it easily for specific validator types in future.
