Expected Behavior vs Actual Behavior

The expected behavior was getting the m3u8 for that playlist, but instead got an error of FileNotFound with the slashes converted to double backslashes.

Steps to reproduce - Ensure to include actual links!

1. Command inputted: spotdl download all-user-playlists --user-auth --m3u "{list}"
2. Every song seems to get downloaded
3. Gets crashed when the program finds a playlists containing slashes (/)
