Fix restarting issues

Browse source 
* exwm-workspace.el (exwm-workspace--confirm-kill-emacs): Prompt for
unsaved files before restarting; avoid running `server-force-stop'
early; restore the 'client' frame parameter before calling `exwm--exit';
correctly handle emacsclient.

* exwm.el (exwm-restart): Always kill subordinate Emacs instances.
