    Skip DBDuplicateEntry exception in security group creation

    An DBDuplicateEntry expection appeared if it is attempted to
    create secutity groups in more then one thread. In this situation
    at one moment it is trying to be created 2 default security groups
    which is not allowed. In this case exception should skipped with
    a message about failed attempt.
