### Describe the bug

The usage of `LinkGenerator.GetPathByName` will throw exception if there are route handlers from method of the same name but from different scope.

If you don't use `LinkGenerator.GetPathByName` on `GreetingPage` inferred route name, it works fine.

### To Reproduce

``` csharp
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Routing;

static IResult Index(LinkGenerator linker) =>
Results.Text(@$"

• About


• About Anne


• About Babka


• Greet Babka

" , "text/html");

static IResult AboutPage(string? name) => Results.Text(@$"

About {name}

" , "text/html");
static IResult GreetingPage(string? name) => Results.Text(@$"

Hi {name}

" , "text/html");

var app = WebApplication.Create();

app.Map("/", Index);
app.Map("/about", AboutPage);
app.Map("/greet", GreetingPage);
app.Map("/greet2", Pages.GreetingPage);
app.Run();

public static class Pages
{
public static IResult GreetingPage(string? name) => Results.Text(@$"

Hi {name}

" , "text/html");
}
```

### Exceptions (if any)
