Issue description

An error is raised when removing/freeing a scene/node that is in MultiplayerSpawner's auto spawn list and client is set as authority.

Steps to reproduce

1. Create an ENet mutliplayer connection over localhost using Godot's high level multiplayer peer.
2. Add some nodes/scenes to the tree that are in MultiplayerSpawner's auto spawn list and set the clients as their authorities when applicable.
3. Start erasing the added nodes.
4. You'll see that when erasing some of the nodes that the error is raised.

Update. It looks like this works as long as the clients aren't set as the multiplayer authority. My understanding is that even if setting clients as the authorities, this should still work in some way as I was following this nice tutorial by Gwizz and he does something similar (which I've also tried but got an ERR_UNAUTHORIZED error raised): https://www.youtube.com/watch?v=M0LJ9EsS_Ak
