[TrevorPilley]

When throwing an ODataException, set the target to an appropriate value to help indicate where the error relates to (e.g. a property, EdmType or query option).

Requires:

• Set the ODataException.Target to an appropriate value Net-Http-OData/Net.Http.WebApi.OData#155
• Set the ODataException.Target to an appropriate value Net-Http-OData/Net.Http.OData#13
