Describe the bug
After adding hidden extension to questionnaire, it does not hide questionnaire item while rendering the ui.

"extension": [
{
"url": "http://hl7.org/fhir/StructureDefinition/questionnaire-hidden",
"valueBoolean": "true"
}
],

• If hidden extension is true, then question item will not be shown irrespective of whether it enabled or not.
• If hidden extension is true and question item is enabled, then initial answers (if present) will be part of questionnaire response.
• If hidden extension is false or not present, and question item is enabled, then question item will be shown.
• If hidden extension is false or not present, and question item is not enabled, then question item will not be shown.
