PlaybackTrackChanged does not fire immediately on Android (unlike iOS)

[taylorakin17]

Describe the Bug When a track ends on Android, the playbackTrackChanged event does not fire immediately every time (which is inconsistent with how iOS functions, playbackTrackChanged fires immediately every time in my testing). The context within which we discovered this (and when it becomes the most evident) is having a Trackplayer.pause() in the listener for Event.PlaybackTrackChanged. The next two sections have more detail for how to reproduce.

Steps To Reproduce

1. Once you have the example app set up, put Trackplayer.pause() in Track player listener for Event.PlaybackTrackChanged.
2. Play a few tracks and observe that the next track begins before it gets paused many times.

Code To Reproduce

 TrackPlayer.addEventListener(
    Event.PlaybackTrackChanged,
    async ({ track, nextTrack, position }) => {
       await Trackplayer.pause();
  }
)

Environment Info: This happens both on Simulators and on actual devices. We are currently testing on RNTP 2.2.0 rc4, but the problem also occurs in RNTP v1.

Verified that this is not occurring in https://github.com/doublesymmetry/react-native-track-player/pull/1713 – the tracks immediately pause when pressing the. next button.
