Not all tracks of a playlist are retrieved

[danielvijge]

In the current implementation (version 0.15) the tracks of a playlists are parsed from the tracks array of the playlist API call. However, this array might not contain all tracks if the playlist contain many tracks.
Instead, the all the tracks can be retrieved via the URL mentioned in tracks_uri. This URL contains a collection, and optionally a next_href for the next collection or tracks.
