On the demo site (http://uat01.openmrs.org:8080/openmrs/), when searching concept by ID, it displays double results because it's finding the same concept two different ways - once with internal ID and the other with its mapping code.
Steps to reproduce:
- Go to concept search on http://uat01.openmrs.org:8080/openmrs/
- Type in concept id (116128)
- Two "malaria" are displayed on the search result. See Screen Shot 2016-03-31 at 4.10.44 PM.png.
