Playlist members list does not update members list

[LuisACorreaCSUMB]

Members numbers and list does not update if people remove it. Tested with Rawrs & You

This thing actually has not been implemented yet, but the logic goes like this:

• If you are part of a playlist and NOT the owner, you can delete a playlist from your list
• Currently if you delete this playlist, you are actually not removed from the list of members in the playlist

Expected Outcome If I delete a playlist on my app, I don't want to be a part of it anymore and should remove the user reference from the playlist document

Actual Outcome The playlist is removed from the user doc, but the user is never removed from the members list of a playlist
