Fixed InputActionReference not being set when attempting to set it on a Prefab or ScriptableObject

Thank you, it was a bit of a pain, I had to cast from ScriptableObject to InputActionReference, it was not clean.

Nice, been waiting for this update! The InputActionReference issue on prefabs was really annoying in my project. Had to work around it with some hacky solutions before.

Quick question tho - does this also fix the case where you duplicate a prefab and the references get messed up? That was driving me crazy last week lol
