[RPi0][pushbutton.py] VLC volume is saved only when VLC is playing

[Darmur]

Describe the bug:

I have my Assistant based on RPi0 with two powerful speakers. If I put the music volume at 100%, the two microphones are saturated and the trigger "snowboy" is not recognized anymore... basically I can't lower the volume. If I press the button to stop music, I can't save a different music volume for next playback, because the file .mediavolume.json is updated only when VLC is playing. The only way is to SSH and manually edit that file.

Some modification can be done to the pushbutton.py code (and to main.py as well) to be able to save the .mediavolume.json file even if VLC is not playing
