non-IFD URLs not handled correctly for on-Prem

[janis-veinbergs]

Given I provide non-IFD URL to ServiceClient constructor:

ServiceClient serviceClient = new(new Uri("https://crm.example.com/org"), app.CustomTokenProvider, logger: Logger);
WhoAmIResponse resp = (WhoAmIResponse)serviceClient.Execute(new WhoAmIRequest());

1. DVSC successfully acquires access_token from /adfs/oauth2/token
2. DVSC issues request to https://crm.example.com/XRMServices/2011/Organization.svc/web?SDKClientVersion=9.2.49.4384

The request contains proper Authorization bearer token, however the request failed to append /org after host part, thus failing the request.

I'v seen code account for IFD style and non-IFD style URLs:

PowerPlatform-DataverseServiceClient/src/GeneralTools/DataverseClient/Client/Utils/Utils.cs

Lines 103 to 118 in 447f9dc

	isOnPrem = true;
	//Setting organization for the AD/Onpremise Oauth/IFD
	if (serviceUri.Segments.Count() >= 2)
	{
	organizationName = serviceUri.Segments[1].TrimEnd('/'); // Fix for bug 294040 http://vstfmbs:8080/tfs/web/wi.aspx?pcguid=12e6d33f-1461-4da4-b3d9-5517a4567489&id=294040
	}else
	{
	// IFD style.
	var segementsList = serviceUri.DnsSafeHost.Split('.');
	if ( segementsList.Length > 1)
	{
	organizationName = segementsList[0];
	}
	}
	}

So I thought it should work with non-IFD urls.
