Deleting reference variable will result in unusable picker appearing on resolve nodes

REGRESSION: No

When deleting a reference variable, any resolve node pins using it will have a picker added, which won't have anything listed in their dropdown.

This isn't consistent with what happens if the user just breaks the link, which simply reverts the pin to a wildcard.

Refreshing the node fixes the issue.

1. Open QAGame in editor.
2. Open the level blueprint.
3. Add an Actor > Object Reference variable.
4. Drag the variable into the Event Graph as a Get.
5. Drag off the Get node and add a Resolve Soft Reference node.
6. Delete the variable from My Blueprints.

RESULT

The empty resolve node pin will have a picker added that won't be populated.

WORKAROUND

Refreshing the node will remove the picker.
