Description

Pre-requisite

On Atlas v0.8: Create few entities say entity1 and classifications say tag1. Associate tag1 to entity1.

Steps to duplicate on Atlas v1.0

• Perform migration import.
• From the web ui select tag1, notice that entity1 is displayed. 
• Attempt to remove tag1 from entity1.

Expected result: tag1 should be removed from entity1.

Actual result: tag1 is not removed. Server logs show 'No classifications associated with entity.'

Root cause: Imported edges that associate vertex with classification vertex do not have __isPropagate property set. The EntityGraphMapper.deleteClassification calls getTraitNames with isPropagate set to false. This makes the call return with no entities. The deletion thus fails.
