The fix was for db/migrate/20140122043508_add_meta_category.rb only, there are few more files with that problem. I think 20141014191645_fix_tos_name.rb does it properly:
class FixTosName < ActiveRecord::Migration
def up
execute ActiveRecord::Base.sql_fragment('UPDATE user_fields SET name = ? WHERE name = ?', I18n.t('terms_of_service.title'), I18n.t("terms_of_service.signup_form_message"))
end
end
