plug crashes with gnome-settings-daemon 3.34 (removed GSettings key)

[decathorpe]

Looks like GNOME people monkey'd around with gnome-settings-daemon 3.34 again (sigh), and removed or renamed the locate-pointer key from GSettings:

io.elementary.switchboard:7969): GLib-GIO-ERROR **: 13:45:12.561: Settings schema 'org.gnome.settings-daemon.peripherals.mouse' does not contain a key named 'locate-pointer'

This leads to a crash when opening the Mouse & Touchpad plug.

Any idea how to resolve this issue? Conditional compilation for g-s-d >= 3.34? I mean, ubuntu 20.04 LTS will have this change too, I guess ... unless they do compatibility downstream patches again

Looks like the plugin was removed because it moved to the compositor for Wayland: GNOME/gnome-settings-daemon@6dff93a

So we should probably check for the existence of the key and not show the setting if it doesn't exists.
