fix scrobble not working when play a playlist

[youthlin]

Describe the changes you made

Since there is a replayDetectionTimer, So when the song played end, it would be set to replay, and call the pause() method. So that this.pausedOn will not be null.
Then will play the next song on the playlist, and call the start() method. However, when update() called, this.pausedOn == null is false, so this.setTrigger is not called. This make the 2nd and the rest in the playlist would NOT be scrobbled.

So when start called, we should set this.pausedOn to null~

Normally the connector should not be pausing as it goes to a new song so I think this bug might only be happening with a handful of connectors.

This fix should make the core more robust, and I don’t see any situation where it can break anything, so LGTM, but I want another reviewer to look at it too in case I missed some obscure gotcha.

Yes, the 163-music connector watch the a[data-action="play"] element, when the played song changed, the button would changed from data-action="pause"(when play) to data-action="play"(when switch a song) and to data-action="pause"(when the new song played)

Can't think of any edge cases :/
