Clear CanvasShutdownObserver::mCanvas when the canvas goes away.
This is fallout from Bug 1167235 - Use a fast method of double buffering for canvas.
It is possible for the CanvasRenderingContext2D to be destroyed while we're in the
middle of the call to nsObserverService::NotifyObservers() for shutdown.
This leaves the shutdown observer with a dangling pointer to the canvas, so this
patch explicitly clears the pointer when the context goes away.
