[Android] notification is missing skip (±15s) buttons and the Previous button in a playlist

[FedericaGonzalez03]

Describe the Bug

On Android, two remote-control buttons are missing from the notification / lock screen (both work fine on iOS):

1. The skip forward / backward (±15s) buttons never appear while the app is in the background.
2. In a playlist (multi-track queue), only the Next button ever appears — the Previous button never shows, on any track (not just the first one). This used to work on v4, where I managed the Previous/Next controls manually (updating capabilities per track); after migrating to v5 the Previous button stopped showing up in the notification even when it's included in capabilities.

Steps To Reproduce

Issue 1 — skip buttons:

1. Set up a single track with skip commands:

TrackPlayer.setCommands({
  capabilities: [PlayerCommand.PlayPause, PlayerCommand.Seek, PlayerCommand.SkipForward, PlayerCommand.SkipBackward],
  forwardInterval: 15,
  backwardInterval: 15,
});

2. Start playback, send the app to the background, and look at the notification / lock screen.
3. → The ±15s skip buttons are not shown (only play/pause). On iOS they appear correctly.

Issue 2 — Previous button in a playlist:

1. Set up a queue with several tracks:

TrackPlayer.setCommands({
  capabilities: [PlayerCommand.PlayPause, PlayerCommand.Seek, PlayerCommand.Previous, PlayerCommand.Next],
});

2. Start playback and skip to the 2nd or 3rd track.
3. Look at the notification / lock screen.
4. → Only Next is shown. Previous never appears, even when there is a previous track in the queue and Previous is set in capabilities. On iOS both appear correctly. This worked on v4 (I was updating the Previous/Next capabilities manually per track); it broke after upgrading to v5.
