Commented Issue: Use the SerializerProvider in the parameter instead of RawValueSerializerProvider [970]

In the ODataMediaTypeFormatters.cs file, in the Create method

CreateRawValue(new RawValueSerializerProvider(), deserializerProvider) uses it's own SerializerProvider instead of the one provided by the the parameter.

Refactor the code so that the serializer provided in the parameter is used.
