If "Esc" is pressed, the callbacks to handle the `focus-out` signal are called after the `cc_password_dialog_dispose` function. This leads to segfaults, because the `user` variable is already cleared. Let's simply do not continue if `user == NULL` to fix those crashes. Closes: https://gitlab.gnome.org/GNOME/gnome-control-center/issues/563
