core: Hide close dialog before destroying

The MetaCloseDialog implementation object may stay artifically alive
for a longer period. This was usually fine till gnome-shell commit
b03bcc85aad, as the check_alive() timeout will keep running even
though the window went unmanaged/destroyed, leading to crashes.

In order to fix this, forcibly hide the dialog if it is visible and
the window is being unmanaged, so the timeout is stopped in time.
