Security Group UI failure for older organizations with no security group

[russellb]

Describe the bug

The security group page on try.nexodus.io does not work for me. It appears to be because one of my organizations does not have a security group. I see the following error on the page:

index-e7d709e3.js:273 Error: Error: Could not fetch https://api.try.nexodus.io/api/organizations/b272fb0d-3bb0-4f56-8519-d853c9efc854/security_group/00000000-0000-0000-0000-000000000000, status: 404

How to Reproduce

Try to view the security groups UI from an account created before security groups support was added. I'm not sure if it's possible to modify an org to have an empty security group field, but that would work too.

Expected Behavior

get the security group page that allows editing rules
