aws_db_option_group.this: value of 'count' cannot be computed

[kanewinter]

When option_group_name is set it causes this error:
module.rds.module.db_option_group.aws_db_option_group.this: aws_db_option_group.this: value of 'count' cannot be computed
This makes it impossible to select a pre-existing option group.
