    Allow deletion of backups where the service is None

    If a backup is created while both cinder-backup and rabbitmq
    are not running, backup records are created in the database with a
    service entry of None.

    There is no actual backup data created on the service, since the service
    isn't running. This fix allows removal of these records without an error
    when a delete backup request is received.

    This fix also ensures backup status is set to error in the event of
    an exception during a delete.

    Fixes bug #1162908
