Fix bugs on managing/unmanaging X windows

Browse source 
* exwm-manage.el (exwm-manage--scan): Unmap X windows before managing them.

(exwm-manage--on-UnmapNotify): Do not ignore synthetic UnmapNotify events
(according to ICCCM).  Do not use the `from-configure' slot which was
mistakenly introduced due to the bug in `exwm-manage--scan'.

* exwm-workspace.el (exwm-workspace--confirm-kill-emacs): Do more cleanups.
