What needs to be done

Several parsed data FHIR paths in message-parser are incorrect, resulting in missing data in the db.

1. Reason for Visit - Our current FHIR path assumes that there is an extension with the reason for visit string (this may have been based off of old data).
2. Disabilities - This FHIR path only pulls the question, should we also be displaying the answers? @austin-hall-skylight
3. Specimen type and Specimen collectio date - Current FHIR paths are outdated

Why it needs to be done

Data is missing in the parsed data when it should be appearing.

Acceptance Criteria

• Update FHIR paths for the fields above, and confirm that the data appears where it exists
• Add / update tests as necessary

Technical Notes

Although the main files to edit are core.json and extended.json in message-parser/app/default_schemas, please check whether the fields exist in any of the other JSON schema files.
