Add a new column before creating rename triggers
MySQL doesn't allow us to create a trigger for a column that doesn't exist yet. Failing with this error: ``` Mysql2::Error: Unknown column 'build_events' in 'NEW': CREATE TRIGGER trigger_6a80c097c862_insert BEFORE INSERT ON `services` FOR EACH ROW SET NEW.`build_events` = NEW.`job_events` ``` Creating the new column before creating the trigger avoids this.
