Due to HttpClient.Delete not having support for HttpContent payloads for which I have raised an Issue in dotnetcore and they are going to update this possibly in later versions. They have recommended using the workaround of using SendAsync. So added a new Delete overload using SendAsync to SpotifyWebApi.cs.
In this, I also have my correction for the Test case where IsNull fails for me when it is an initialized array with no elements.
