Fix: Cache defaults for unique scenes which use the same script (#2676)

Dialogic stores the default values of scene exports for custom layers and portraits (so they can be reset correctly). However it would cache them per-script, even though different scenes can have the same script AND different exports. They are now stored by scene path instead.
