Upgrade to 7.0 has broken the gitlab service

Created by: jbrooksuk

I'm half way through upgrading, just about to restart the gitlab service and got this:

bbtadmin@git:/home/git/gitlab$ sudo service gitlab start
Starting both the GitLab Unicorn and Sidekiq/etc/init.d/gitlab: 178: /etc/init.d/gitlab: /etc/init.d/gitlab: 171: /etc/init.d/gitlab: script/web: not found
script/background_jobs: not found
..............................Waited 30s for the processes to write their pids, something probably went wrong.
bbtadmin@git:/home/git/gitlab$ sudo service nginx restart
bbtadmin@git:/home/git/gitlab$ sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
Instance method "lock!" is already defined in ActiveRecord::Base, use generic helper instead or set StateMachine::Machine.ignore_method_conflicts = true.
