Should ValueProviders return null when the key is present but the value is null #1609

It looks like our value providers have a change in behavior when the key is present but the value is null.

Ex: /api/Products?id=

The value provider for query string will return a null value provider result. This is a change from MVC5/WebAPI2.

See https://github.com/aspnet/Mvc/blob/dev/test/Microsoft.AspNet.Mvc.ModelBinding.Test/ValueProviders/ReadableStringCollectionValueProviderTests.cs#L161

Yes, that was the intent.
