Recently played call uses SimpleTrack instead of Track

[Nielssg]

Describe the bug
The getRecentlyPlayed call returns a PlayHistory object, which contains a SimpleTrack. It appears however that the Spotify API returns a Track rather than a SimpleTrack.

To Reproduce
This can be tried out by visiting the Spotify API docs and using the try out option to get some data. This data has tracks which have an album, indicating that it is in fact a Track object.

Expected behavior
PlayHistory should contain a Track object, not a SimpleTrack object. This might be a recent change from Spotify which has not been documented
