2829938 - An empty EntitySet is represented as an empty JSON array instead of 'null'

After upgrade, the OData JSON serializer handles empty result arrays in a different way. Previously it would be 'null', now it is an empty JSON array.

For example, previously it was:

"Products" : null

Now it is:

"Products" : {
      "results" : [

      ]
    }
