The Get Class Default node's Hide Unconnected Pins option no longer hides the appropriate pins

The Hide Unconnected Pins option in the Get Class Defaults node no longer hides any of the pins.

Tested in //UE4/Release-4.25 @ CL 14469661 and this did not occur so marking as a Regression.

1. Create or open a project
2. Create an Actor blueprint
3. Add a variable of any type, set at its default value
4. Add a Get Class Defaults node into the event graph
5. Select the node and in the details panel, select Hide Unconnected Pins

RESULTS:

EXPECTED:

The Hide Unconnected Pins option would hide any pins that aren't connected
