fix: URL of reference type search

# Problems
- lodash set generates nested objects, while queryBuilder[field] does not,
resulting in double query json and unable to find anything.
- The match is {resourceType}/{id}

# Solutions
- Only keep queryBuilder[field]
- Change to URL

models/FHIR/queryBuild.js
