Description

During the deserialization of deep instert payloads we create an ExpandOption object to help applications create the payload they have to send back to the client. Incase the deep insert payload contains a feed we create duplicate expand items for every entry within the inner feed. Since the serializer olny looks at the outer most ExpandOption the payload is incorrect.

Solution: Prevent duplicate creation and have one SelectItem for every NavigationProperty.
