Our schema version is in the future!

https://gitlab.com/gitlab-org/gitlab-ce/blob/master/db/schema.rb#L14

This is because of the migrations in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/12280, so this is my fault.

What we need to do:

1. Add the same migrations with sensible timestamps (in the past).
2. Ensure that they don't break if the future migrations have already run on the DB.
