So, if do-release-upgrade -d is used, upstart is in fact upgraded before mysql, and this problem does not appear. I'm lowering this to Medium, since that is by far the preffered method.
Unfortunately a much more serious issue turned up, where /run/mysql/mysqld.sock is not writable due to the apparmor profile.
