Next/Previous track buttons not updated when current track's position in the playlist changes

[Sean Talbot]

Version: 0.8.1-1~566~lucid1

The 'next' and 'previous' track buttons should have their state updated whenever the current track's playlist position is changed, but they are not.

Steps to reproduce:

1. Add at least two tracks to the playlist.
2. Play the first track in the playlist. The 'previous track' button is unselectable; the 'next track' button is selectable.
3. Drag the playing track to the end of the playlist. The 'previous track' button is still unselectable (even though there are tracks before it) and the 'next track' button is selectable (even though there are no tracks enqueued ahead of it).

The inverse occurs when you move the last track to the start.

Thanks, indeed this this a bug.
