Subject: [PATCH] fix #31: handle discogs tracks in case of sub-tracks

in case of sub-tracks (at least for http://api.discogs.com/releases/5880212 ),
json field "position" is "" so previous code ignored the track.

The solution here is to use first sub-track position which is good enough to detect change of CD numbers.
