/* MIGRATION TO CLEAN PRODUCTION DATA
*
* cleanup the login_user_backups table as far a possible.
* Since the passphrase changed and its type is not detectable
* this whole thing is a pitfall
* cleanup the login_user_backups.
* Delete data with no reference in login_users table and
* delete the right one of the duplicate keys
*/
