Issue:
Index.html update breaks acl link header
Since #806 the acl link for a container is now going to point to `/index.html.acl` instead of `/.acl` (discovered by integration test when adding a default index.html for the root container).

Pull request description:
fix: Keep container metadata when returning index.html representation
Closes #822
