Title: Fixed issue where GKLeaderboard object was trying to be encoded.

... set to the saved GKLeaderboard object.

Fixing this seemed to cause the object to be removed from the
_leaderboards ivar, so I had to add the check to prevent an
NSRangeException. Please feel free to clean up my solution if you can
discover why this is occurring.
