indicator-network, under systemd, starts on u7 when it shouldn't

indicator-network is meant to not start on u7, it should only be wanted by u8 session.

$ cat /usr/lib/systemd/user/indicator-network.service
[Unit]
Description=Indicator Network Backend
PartOf=graphical-session.target
After=indicators-pre.target
Wants=indicator-network-secret-agent.service

[Service]
ExecStart=/usr/lib/x86_64-linux-gnu/indicator-network/indicator-network-service
Restart=on-failure

vs in upstart user session:
pre-start script
 # NOTE: Only used on Unity8 today, not 7
 # Still allows manual starting
 if [ "x$DESKTOP_SESSION" != "xubuntu-touch" ] &&
    [ "x$DESKTOP_SESSION" != "xunity8" ]; then
  if [ "x$UPSTART_EVENTS" != "x" ] ; then
   stop; exit 0
  fi
 fi
end script
