EE master is broken

EE master is currently red because of the following:

1. db/migrate/20181211092510_add_name_author_id_and_sha_to_releases.rb is apparently creating columns that already exist in https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/134700157
   • @nolith: you appear to have added this migration, please investigate what is going on here.
   • MR: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23763
     • Merge request itself looks fine.
2. .pot files are not updated: https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/134557348
   • @reprazent You seem to have made the last changes related to this, but in https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/134654143 the build still fails. Please investigate.
3. https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/134638196: same database error as we run into https://gitlab.com/gitlab-org/gitlab-ce/issues/55232.
   • We need to get this issue prioritised, since it keeps happening. @marin how can we make this happen?
