Title: Return null from GetPairs/GetNameValueCollection if value is null

During deserialization of a `List<>` property, Json.net first checks to see if the property is `null`. If _not_, then it avoids calling the property `set` and simply calls `Add()` to the value returned by the `get`.

If the property _is_ null, then it will create the list, and then call the `set` on that property.

This change makes the collection properties of the `Error` class work with Json.net. `JavascriptSerializer` is unaffected and should work as it did previously.
