After some further research, I found that the still-enabled instance of 
nm-applet is auto-starting from /etc/xdg/autostart/Network.desktop.

But I also found that /etc/xdg/lxsession/Lubuntu/autostart and 
~/.config/lxsession/Lubuntu/autostart are both empty files.  So in 
lxsession-default-apps, when I set changed Network GUI from nm-applet to 
'no', what was it writing that setting to?
