unselected asg_cfg causes an exception

[cugarteblair]

After new DB update a new field for auto scaling group config was added to the orgAccount. It was initialized to 'unselected'.
If the user never explicitly selects the asg_cfg an exception is thrown.
After the first selection it will always have a valid entry.
