Test routes with primitive return types

[ivaylokenov]

The provided expression is not MethodCallExpression. It uses Convert and it should be unwrapped.

Steps to reproduce:

• Action: public int Primitive(object id) => (int)id;
• Test:

MyRouting
    .Configuration()
    .ShouldMap("/Home/Primitive/12")
    .To<HomeController>(c => c.Primitive(12));

The above method does not recognize the id property correctly.

Closing since this parameter binding is expected behavior in ASP.NET Core MVC.
