Description of your issue, suggested solution and other information

When the URL to a Youtube video has both a video and a playlist, and I'm using --no-playlist, I expect it to choose the video and not the playlist.

When it's a URL of the form youtube.com/watch?v=abc&list=xyz it works as I expect: the single video is downloaded ("Downloading just video abc because of --no-playlist").

When it's a URL of the form youtu.be/abc?list=xyz the whole list is downloaded. I believe in this case only the video abc should be downloaded.
