After Creating Child Device With Twin, Parent Device wont show child device

- **OS, version, SKU and CPU architecture used:** Windows 11 x64
- **Application's .NET Target Framework :** NET 6
- **Device:** Amd64 Laptop
- **SDK version used:** 1.39

After creating an Azure IoT Child device specifying it's parent scope and using the following method:

`registryManager.AddDeviceWithTwinAsync(device, twin)`

Notice the twin only contains desired properties and tags values.

In azure IoT Hub the device correctly shows the relation with its parent (you can see "This device has a parent assigned")
Also the parent scope points to the parent device.

**But when selecting the parent it's not showing any child device.**

Using the following method (no twin specification) does not generate the problem:

`registryManager.AddDeviceAsync(device)`

Start by reproducing the issue with Azure IoT SDK 1.39 on .NET 6, comparing registryManager.AddDeviceWithTwinAsync(device, twin) with registryManager.AddDeviceAsync(device). Inspect how the two methods create the parent-child relationship and twin, then verify that the parent shows the child while the child retains its desired properties and tags.
