          Issue Type: Bug
            Reporter: Cade Parker


I'm using Atlas version 0.8.1. When trying to delete an entity by id (DELETE 
/v2/entity/guid/{guid}), the server throws the following 
EntityNotFoundException:

This bug seems exactly like the issue in ATLAS-931. The API resources look like 
they were refactored in 0.7 -> 0.8, and I believe that the error handling logic 
wasn't translated properly.

The same error is thrown if I try to remove an entity reference from an 
attribute that contains a list of references to an "ownedRef" entity (E.g. 
removing a column from a table entity).The exception is thrown, claiming it 
cannot find the removed column entity in the graph.
