Purpose of this PR
Fixes the issue where NetworkManager would not clean up if an exception was thrown while it was starting. This could result in a host or server not completing the start process yet would still have internal systems (i.e. NetworkConnectionManager, NetworkMessageManager, and UnityTransport) initialized. If a client attempted to connect to a server or host in this state it could result in the server or host logging the following error message:
[Netcode] A ConnectionRequestMessage was received from the server on the client side.
