I'm slightly confused by the logic here. Why is a user's systemd even 
running before they've logged in? If the user has lingering enabled, 
then it might have a systemd instance from that, but it certainly 
shouldn't reach any plasma-core.target as the login GUI should be 
running as a different user to your user I would have thought?

e.g. under gnome, the login GUI runs as the "gdm" user. That user has a 
systemd --user instance, and runs various things but only once a real 
user has logged in will it's own systemd instance start and reach the 
appropriate targets.

It seems a bit odd to me that your users' plasma-core.target has been 
run when your user hasn't even logged in yet. I think something is odd 
there, possible combined with user lingering and perhaps plasma-core 
being the default target for your user when it shouldn't be...

Hope this helps you debug things.
