aws_iam_policy_document.source_policy_documents that contain multiple conditions are dropped on output

[mikeknoll]

I am using aws_iam_policy_document to combine multiple JSON policy documents into a single aws_organizations_policy. Everything worked until I introduced a policy with a StringNotLike and Null condition. The Null condition is being dropped.
