BindChildPrefabsTo() destroys transform instead of gameobject #3

GameObjectExtensions.BindChildPrefabsTo() should destroy instantiated prefabs during element removal from ReactiveCollection.
But GameObjectExtensions.onElementRemoved() destorys transform of instantiated prefab instead of gameobject.
This is not working if instance has RectTransfom.
There are 2 cases:

1. RectTransfom destoryed and replaced with Transform.
2. RectTransform not destroyed because there is another component depending on it.

In both cases actual gameobject not destroyed.

I suggest replcaing impelmentation of GameObjectExtensions.onElementRemoved() to:

void onElementRemoved(CollectionRemoveEvent<T> data)
{
    var existingChild = input.transform.GetChild(data.Index).gameObject;
    onChildRemoving?.Invoke(data.Value, existingChild);
    GameObject.Destroy(existingChild);
}
