Option create_security_group can't be false currently

[stefanstaykov]

Found a bug? Maybe our Slack Community can help.

Describe the Bug

Setting create_security_group to false will not work as the module currently expects module.aws_security_group.id every time.

Expected Behavior

Setting create_security_group to false and associated_security_group_ids to a list of string should associate the eb environment with the selected security groups but it fails because module.aws_security_group.id can't be null.

Steps to Reproduce

Steps to reproduce the behavior:
Set:
create_security_group = false
associated_security_group_ids = ['some-string']
Run:
terraform plan
