listFix() v2.9.0

Steps:

1. Open a playlist for editing in the editor. The playlist should contain a mix of OK tracks (already matched tracks), plus Exclamation-marked tracks (those tracks for which matches are still to be found):

2. Activate the repair (magic wand) on the playlist.

3. Once the all the appropriate matches have been found, close the last processing dialogue, i.e. "Select closest matches" by pressing the cancel button to return to the playlist.

4. Issue upon return to the playlist: the playlist cannot be refreshed. The refresh button is unavailable/dulled. To refresh the playlist, it has to be closed first, and then reopened.
