window: free close dialog before unmanaging window from compositor

When an application stops responding, the shell darkens its windows.

If a window from a not-responding application gets unmanaged
then the shell will currently throw an exception trying to retrieve
the now-dissociated window actor.

That leads to a "stuck window" ghost on screen and a traceback
in the log.

This commit addresses the problem by making sure the effect is cleaned
up before the actor is disocciated from its window.
