Description

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:

2017-09-22 20:47:25,104 ERROR - [pool-1-thread-5 - a5dca07b-477d-4876-a4a2-9682a1280071:] ~ Exception while getting a typed reference for the entity  (AtlasInstanceConverter:114)

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, but the column entity is still retrievable via the REST API (the status remains ACTIVE), and the table entity is not updated.
