[iOS] Authenticate is not returning to app after authorizing on Spotify App

Hi, I've been trying to debug this issue for 3 days now. On iOS when you call authenticate, the Spotify app will open with no problems, a tick mark will appear that authorization worked, after that, Spotify doesn't redirect back to the application.

If you need something else to narrow down the issue please ask!

Thanks @cjam for this library!
