ServerOnly does not clean up network objects on StopServer

[uweeby]

Please explain the suggested feature in detail.
ServerOnly does not clean up network objects on StopServer. Can be seen in the ChangeScene example. Start as ServerOnly. StopServer. See the network objects remain.

How exactly does this keep you from releasing your game right now?
May be part of the cause of #235

Can you suggest a possible solution?
Use similar logic to what the client is using to loop through the Spawned collection and destroy
