Queue highlights every instance of currently playing track

Noticed a small bug in the web interface:

When you have the same track several times in the queue, it will show all instances of it as currently playing:

Not sure if the matching is by name or by uri. In this particular case the two entries are both referring to the same file.

Fixed in the next version (https://github.com/woutervanwijk/Mopidy-MusicBox-Webclient/commit/2c946d4fdd2f98e4d5d02deb7ff564cc27444ffb)
