(fix) bypass root route in lazarus

[gabrielbaltazar]

in Lazarus the Req.Web Request.PathInfo returns empty for the '/' route, so if this route is in the skip route, lazarus was not recognizing it.

  THorse.Use(HorseJWT('my-private-key', THorseJWTConfig.New.SkipRoutes(['/']) ));

  THorse
    .Get('/ping', GetPing)
    .Get('/', GetRoot);
