Upgrade to 4.0.2 breaks SignalR

See original GitHub issue

When upgrading from version LightInject 4.0.0 to 4.0.2 using LightInject.SignalR integration I get the following exception:

Exception of type System.Reflection.TargetInvocationException

I will move SignalR into its own repo and add specific support for Net46

I had to workaround this issue by not using LightInject.SignalR, but manually registering my hub with the SignalR dependency resolver:

var hubConfiguration = new HubConfiguration();
hubConfiguration.Resolver.Register(typeof(MyHub), Container.Create<MyHub>());
app.MapSignalR(hubConfiguration);

This enables constructor injection in the hub, using services already registered in the LightInject Container.
