mpdscribble does not work with streams

[brianclemens]

mpdscribble does not seem to function as expected when mpd is playing from radio streams. Steps to reproduce:

1. Add a radio that provides full track information, mpc load https://lainon.life/radio/cafe.ogg.m3u
2. After mpc play, mpdscribble correctly submits the "now playing" status
3. When the track changes, mpdscribble does nothing
