When songs have the same track number, creating symbolic links does not work properly.

[AndyIbanez]

If two tracks in an album are track 2, and they are both called "Foo Bar", if dsfuplicates detects them as duplicate songs, it will only create one shortcut. Of course, it will create two, but the older one will be replaced by the new one, so the "Create Symbolic Links" feature is currently buggy.
