-Removes duplicate scene that is added during reimport when it is safe to do so.
-Added some safeties to the set_edited_scene() function of the EditorNode script (doesn't check if the signal exists when disconnecting it, and same issue as the next point)
-Adds a safety to the _add_nodes() function of the SceneTreeEditor script (would print an error if the node had its parent changed from the viewport/null, which can happen in plugin scripts)
Could be improved by properly selecting the node directly to restore the node tree, instead of using set_edited_scene() on line 1063 of editor_node.cpp (possible slight efficiency gain)
Fixes #87451
