Volume set to 0 when video ends

Description

When a video is played until the end, any following video will have no sound when volume was < 100.

Steps to reproduce

1. Play any video with volume set to anything between 0 and 100
2. Wait the end of the video, the app return to video grid
3. Play another video (could be the same one)
4. There is no sound
5. any volume change will restore it on phone/tablet, on android tv the only way i found was to go to preferences to kill VLC

Debug

When video ends, PlayerController.restart() is called twice.

• if volume was < 100, in restart(), volume=100 the first time, volume=0 the second time
• if volume was > 100 (150 for instance), in restart(), vol=150 both times

Don't know if that's normal to have volume=0 the second time, or that restart is called twice
