Netcode tutorial doesn't handle multiple MainEntityCamera from different clients but uses HasSingleton<MainEntityCamera>

If you follow the directions in https://github.com/Unity-Technologies/CharacterControllerSamples/blob/master/_Documentation/Tutorial/tutorial-netcodecharacters.md

Everything works in the editor fine, that is until a second client connects. That's when that world creates a 2nd MainEntityCamera entity and the MainCameraSystem breaks.

Considering it's a tutorial for netcode it should be assumed it's for multiplayer and multiple clients.
