What is the current behavior?
RoutedViewHost on UWP uses the IRoutableViewModel type to specify what view model type to return for ViewLocator calls, which ends up failing

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

public interface IRoutableFooViewModel : IRoutableViewModel { }

public class RoutableFooViewModel : ReactiveObject, IRoutableFooViewModel
{
    public IScreen HostScreen { get; set; }
    public string UrlPathSegment { get; set; }
}

public class RoutableFooView : IViewFor<IRoutableFooViewModel>
{
    object IViewFor.ViewModel
    {
        get { return ViewModel; }
        set { ViewModel = (IRoutableFooViewModel)value; }
    }
    public IRoutableFooViewModel ViewModel { get; set; }
}

public void CanResolveViewFromViewModelWithIRoutableViewModelType()
{
	var resolver = new ModernDependencyResolver();

	resolver.InitializeSplat();
	resolver.InitializeReactiveUI();
	resolver.Register(() => new RoutableFooView(), typeof(IViewFor<IRoutableFooViewModel>));

	using (resolver.WithResolver()) {
		var fixture = new DefaultViewLocator();
		var vm = new RoutableFooViewModel();

		var result = fixture.ResolveView<IRoutableViewModel>(vm);
		Assert.IsType<RoutableFooView>(result);
	}
}

What is the expected behavior?
That this type can be resolved...

What is the motivation / use case for changing the behavior?

Which versions of ReactiveUI, and which platform / OS are affected by this issue? Did this work in previous versions of ReativeUI? Please also test with the latest stable and snapshot (http://docs.reactiveui.net/en/contributing/snapshot/index.html) versions.
Any version other than 7.2.

Other information (e.g. stacktraces, related issues, suggestions how to fix)
I think the only change required would be to change ViewLocator to use GetType() rather than typeof(T) on line 170.
