Are you sure you get them? Are they not started on-demand as soon as you
switch to them? This is handled by autovt at .serivce (which is just a
symlink to getty at .service by default).
Systemd handles this magically. Simply set: NAutoVTs=0 in logind.conf to
Make sure however you do enabled at least one getty manually if you do
this. I'm not sure you test.target did that. You'll want a
test.target.wants/getty at tty1.service symlink (pointing to your
getty at .service file.

Well consolekit I agree with, but polkit is likely loaded automatically
when you start running systemctl commands. It uses polkit to decide
whether or not you are allowed to do stuff.
However, consolekit is likely started as a consequence of logging in.
Chances are you have some pam modules (i.e. pam_ck_connector) in
whatever pam config you're using to login.
