xapp status: Make sure the recording icon size is set, disconnect

the recording signal when the applet is removed.

The indicator had the correct size when Cinnamon started because
it would receive an icon-theme-changed signal. If it got reloaded,
that signal wasn't sent, so refresh() was never called on the
indicator box.
