Purpose of this PR
(This is cherry-picked from another PR that is on hold.)
The undo callback of the graphics compositor will throw a null reference error when switching from a scene that is using the compositor to one that is not using it.
Testing status
Switched from a scene that is using the graphics compositor to one that is not. Performed an action and hit undo.
Undo does not throw a null reference anymore.
This is a simple fix, I don't think there is any need for more QA.
