##### SUMMARY
When running `ansible-test sanity --test validate-modules` on a PowerShell module in a collection it will fail to import any module util that is in Ansible itself. This causes issues if it requires access to those utils to build the arg spec as we can see with https://app.shippable.com/github/ansible-collections/ansible.windows/runs/16/5/console.
