NancyModule.Context null when attempting to register all modules at startup with Autofac 4

[gkinsman]

Hi,

I've run into an issue that appears to be new with Autofac 4. When Nancy calls GetAllModules at startup to register each module's routes, it fails in the getter of NancyModule.Request as the Context in that instance is null.

Given that I'm registering my modules like this with properties autowired, it could be that a change to property wiring in Autofac has broken this registration. Not sure!

 builder.RegisterAssemblyTypes(typeof(AppNancyBootstrapper).Assembly)
                .AsSelf()
                .As<INancyModule>()
                .PropertiesAutowired(PropertyWiringOptions.PreserveSetValues);

Stack Trace:

and so on and so on...

I've downgraded to Autofac 3.x for now as a workaround.

Thanks!
