Right, this is not the way you should be doing it.

My /usr/share/tor/tor-service-defaults-torrc file has these lines in it:

CookieAuthentication 1
CookieAuthFileGroupReadable 1
CookieAuthFile /var/run/tor/control.authcookie

So you shouldn't be needing to add any lines to your /etc/tor/torrc
file.

This sounds bad too. In fact, it sounds like one of those "you broke
the package, and now you get to keep both pieces" situations. :)

I believe that the Tor deb, including the one intended for jessie,
should work with systemd well:
https://gitweb.torproject.org/debian/tor.git/tree/debian/changelog?id=debian-tor-0.2.8.9-1
Am I mistaken?

That said, be sure you're using a recent Tor deb:
https://www.torproject.org/docs/debian
and not the ancient Tor 0.2.5.x in vanilla jessie.
