Deactivate touch selection when active client is invalidated.

Hide touch selection handles and menu after if the active client managed
by TouchSelectionControllerClientAura is invalidated. This is to prevent
stray handles and menu staying around after the active client is
destroyed (e.g. after reloading a web page where the active client
corresponds to an iframe).
