[decorations] Don't recreate Renderer once the Compositor is destroyed

Browse source 
If we get a compositingToggled because the Compositor is going down we
don't need to recreate the Renderer as KWin as a whole is going down.

Thus we disconnect the compositingToggled connection when the Compositor
is about to be destroyed.
