AutofacContrib.DynamicProxy2: Internal interfaces are not intercepted (and no exception)

[GoogleCodeExporter]

What steps will reproduce the problem?

            var builder = new ContainerBuilder();
                builder
                .RegisterType<SomeConcreteType>()
                .EnableInterfaceInterceptors()
                .InterceptedBy(typeof(SomeInterceptor))
                .As<ISomeInternalInterface>();

            builder.Build().Resolve<ISomeInternalInterface>().SomeMethod(); // <-- will not be intercepted

DynamicProxy2 is not able to proxy internal interfaces. I guess that's why the 
interception doesn't work. But an exception would be nice, because the 
interception just silently disables itself :)

Looks like it was checking to ensure the interception was for interfaces but 
not that it was also visible. I've updated this so you'll get an exception when 
you resolve an incorrectly registered component and the exception explains what 
to check for. Since the actual proxy isn't generated until resolve time, I 
can't really provide a container build-time exception.
