World crash when connecting `DynamicVariableObjectInput<Slot>` into `FireOnRefChange<Slot>` ProtoFlux node and then reparenting the nodes into a DynamicVariableSpace after the referenced dynamic slot has been destroyed

Describe the bug?

Plugging a destroyed slot ref into FireOnRefChange<Slot> under the following conditions causes a world crash.

To Reproduce

Link to public repro folder: resrec:///U-Nytra/R-F824528305BBB70CDD09A61F41D07C33D9F528EB8FC3A9C418BDF874363F3E15

In the folder there are two items. One of them is called Test Root and this is the one which causes the crash. The other is called Test Root With Workaround with a workaround applied which avoids the crash.

1) Spawn the Test Root item from the folder.

2) Open the spawned slot in an inspector and select the Space child slot.

3) Create a new EmptyObject slot and drop the reference to it into the Target dynamic reference variable.

4) Destroy the EmptyObject.

5) Reparent the Flux slot to be a child of the Space slot.

6) World crashes.

Expected behavior

World does not crash.
