[SyncVar] NetworkBehaviours would be cleared if client runs out of visibilty range

[miwarnec]

GameObject, NetworkIdentity are stored by netId internally for that reason.

@vis2k - Is there more to do for this, or not?

fix is in #2957

[miwarnec]

let's see. adding all the sycnvars to Tanks.cs:

        [SyncVar] public GameObject go;
        [SyncVar] public NetworkIdentity ni;
        [SyncVar] public NetworkBehaviour nb;
        [SyncVar] public Tank tn;

generated getters:

    public GameObject Networkgo
    {
        get
        {
            return GetSyncVarGameObject(___goNetId, ref go);
        }
        [param: In]
        set
        {
            GeneratedSyncVarSetter_GameObject(value, ref go, 2uL, null, ref ___goNetId);
        }
    }

    public NetworkIdentity Networkni
    {
        get
        {
            return GetSyncVarNetworkIdentity(___niNetId, ref ni);
        }
        [param: In]
        set
        {
            GeneratedSyncVarSetter_NetworkIdentity(value, ref ni, 4uL, null, ref ___niNetId);
        }
    }

    public NetworkBehaviour Networknb
    {
        get
        {
            return nb;
        }
        [param: In]
        set
        {
            GeneratedSyncVarSetter(value, ref nb, 8uL, null);
        }
    }

    public Tank Networktn
    {
        get
        {
            return GetSyncVarNetworkBehaviour(___tnNetId, ref tn);
        }
        [param: In]
        set
        {
            GeneratedSyncVarSetter_NetworkBehaviour(value, ref tn, 16uL, null, ref ___tnNetId);
        }
    }

=> GO, NI, classes inheriting NB already get looked up by id. => just need to do the same for NetworkBehaviour itself
