Bug Description

[Impact]
The sound panel doesn't deregister a gsettings handle correctly, that may cause crashes:
https://errors.ubuntu.com/problem/f7f4e5f488353a7c6ea085de8a987eecf3c1870e

[Test Case]
1. Open gnome-control-center
2. Select sound settings
3. Select another panel
4. Using dconf-editor toggle com.ubuntu.sound allow-amplified-volume

Expected result:
Nothing happens

Observed result:
Errors shown on command line each time value is toggled OR gnome-control-center crashes.

[Regresion Potential]
Low, we are now cleaning up a reference that was missed.

This is a crash in our 70_allow_sound_above_100.patch patch - the gsettings schema is never unreferenced.
