This fixes a condition where an intermittent db connection could cause invalid site settings to be stored It also removes a catch all we had. Somewhere around Rails 5 `db:create` started wanting full environment this is a problem for Discourse since it needs to boot up data from the db. This removes the catch all and surgically adds a db / redis bypass to db:create task.
