Created Unassigned: MVC routing fails when explicit verb attribute is used on an action [1265]

__NOTE__: this is a regression after yesterday's changes to MVC attribute routing which made some
changes affecting conventional routing too.

Following works:

```
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
}
```

but the following doesn't resulting in 404 Not Found:

```
public class HomeController : Controller
{
[HttpGet] //<---------------------------Note this
public ActionResult Index()
{
return View();
}
}
```
