ACG-Player v2.6.5.3(20190530); The app crashes if I try to add the same song to a playlist.

Project Information

• Repository:
  https://github.com/AugustToko/ACG-Player
• Project Name: ACG-Player

Describe the bug
I created a playlist and added a song to it. Whilst still checking out the playlist feature, I tried to add the same song to the same playlist. The app crashed when I tried that.

To Reproduce

1. To create a playlist, you have to use a song on the list.
2. Click on the 3 dots beside any track/song
3. Click on 'add playlist' option
4. Create a playlist
5. Try to add the same song to the same playlist
6. See error.

Expected behavior
There are two possible outcomes/behaviours that I expected.

• I expected that the app would notify me that the song already exists on the playlist. Or,
• The song is also added to the playlist as a duplicate(this would rarely happen though). But it's not impossible.

Screen recording

Test Environment:

• Device: RedMi Note 5 Pro
