This was left-over in commit 2743f18af, and probably is the real reason why the busy spinner wasn't using the shared AnimatedIcon.Spinner class: The animation there was much slower. Still, let's keep the code as-is for now, if we really need a different animation time, we can add an optional constructor parameter to the Spinner class. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/640
