Atlas UI: Entity Details UI is broken after the changes in ATLAS-58

Entity details and the lineage map are not showing up after the changes introduced for ATLAS-58 commit.
The api call - http://localhost:21000/api/atlas/entity/

{GUID} now returns a 404
UI needs to update the call to
http://localhost:21000/api/atlas/entities/{GUID}

so details come back.

Attaching screen shot .
