ValueSet export is Bad Request

[lmd59]

Summary

Previously a system export with _type=ValueSet had an unexpected file read error. ValueSet should not be allowed to be exported, so

New behavior

Any export request with ValueSet as the type specified in the parameters gives a Bad Request response

Code changes

• export.service update to exclude ValueSet from the types that are supported for export (but not from the types that are supported for storage in the collection creation script)
• exportToNDJson change to properly create the full client id folder to prevent other issues like this

Testing guidance

• npm run check
• npm run start
• Insomnia export requests such as $export?_typeFilter=ValueSet?id=test, $export?_elements=ValueSet.id, $export?_type=ValueSet should all return a 400 specifying ValueSet is unsupported.
