[bugfix]: Fix repeated track scrobbling (#480)

* [bugfix]: Fix repeated track scrobbling

This commit fixes scrobbling tracks that are repeated in the queue (either due
to a REPEAT_ONE or just enqueued multiple times). There are two extra cases:

1. The current player changes. The player alternates from 1 -> 2 -> 1 whenever playback
finishes normally, so this is a sort of epoch that can be used to detect both repeat one
and track being enqueued multiple times.
2. The current index changes. The player gets set back to 1 in a variety of cases (most often
previous/next), so the check in (1) is not enough. However, the index changing will help identify
that this is a new song.

* use unique id instead
