Composite Decorator Graph nodes are not updating titles when changes are made to the properties of a node

Composite Decorator Graph nodes are not updating titles. Upon closing and reopening the Composite Decorator Graph, the nodes do refresh to their properly set title.

Repro Rate: 3/3

Tested this in //UE4/Release-4.27 @ CL#18319896 and the issue did occur there, it is not a regression.

1. Create a new blank BP project
2. Create a behavior tree asset and open it
3. From the Root node, drag and place a Selector node
4. Right-Click the Selector node and add a Composite Decorator onto it
5. Open the Composite's graph editor by double clicking on it
6. In the top-left, create a new Blackboard asset
7. Add an Int key into the Blackboard, named decisionID, and save.
8. Inside the Composite Decorator Graph, place a new Blackboard node, set its Blackboard Key to decisionID, change Key Query to Is Equal To and set the Key Value to 1.

Results: The Blackboard node's name is "Blackboard: SelfActor is Is Set". (or whatever it was when it was added)
Expected: The Blackboard node's name should be "Blackboard: decisionID is Equal To 1".
