serialization: EnableLowerCase() broken

[rjhernandez]

Support for the EnableLowerCase() serialization option seems broken.

Tested using ODataAuthorizationSample.

public static IEdmModel GetEdmModel()
{
  var builder = new ODataConventionModelBuilder();
  builder.EnableLowerCamelCase();
  // ...
  return model;
}

Postman response:

Error:
