Inspector : Fix references to "None" rather than "Source"

Changes.md

@@ -27,6 +27,7 @@ Fixes
 - Widget : Fixed `event.sourceWidget` for DragDropEvents generated from a Qt native drag within the same Gaffer process. This will now reference the `GafferUI.Widget` that the Qt source widget belongs to, if any.
 - Catalogue : Fixed bug which "stole" drags that crossed the image listing but which were destined elsewhere, for instance a drag from the HierarchyView to a PathFilter in the GraphEditor.
 - GadgetWidget : Fixed signal handling bug in `setViewportGadget()`. This could cause the widget to attempt to redraw unnecessarily when the _old_ viewport requested a redraw.
+- AttributeEditor, LightEditor, RenderPassEditor : Fixed warning message which referred to "None" rather than the "Source" scope.
