Subject: [PATCH] overview: Hide the overview on session mode hasOverview
 changes

If the sessionMode does not allow to show the overview, we should also
hide an already visible overview.

This fixes a bug where, if the lockscreen was shown while the overview
was visible, the Ctrl+Alt+Tab popup would allow navigating inside the
overview because the overview actor is still mapped.
