Definition Based Extraction: Issue in extracting repeating order elements

[nsabale7]

Describe the bug Issue during definition based extraction having repeating order elements, such as given in the Patient.name resource having a cardinality ratio [0..*]

Component SDC library

To Reproduce Steps to reproduce the behavior:

1. Use below json as questionnaire string.

{
    "resourceType": "Questionnaire",
    "item": [
                {
                  "linkId": "PR-name",
                  "type": "group",
                  "definition": "http://hl7.org/fhir/StructureDefinition/Patient#Patient.name",
                  "item": [
                    {
                      "linkId": "PR-name-text",
                      "definition": "http://hl7.org/fhir/StructureDefinition/Patient#Patient.name.given",
                      "type": "string",
                      "text": "First Name"
                    },
                    {
                      "linkId": "PR-name-middle",
                      "definition": "http://hl7.org/fhir/StructureDefinition/datatypes#Patient.name.given",
                      "type": "string",
                      "text": "Middle Name"
                    }
                  ]
                }
            ]
}

2. Perform extraction using the questionnaire response
3. Patient.name element will contain only single value in the given field.

Expected behavior Paitent.name element should contain multiple given values as expected.
