Retrieve post ancestors and append to post ancestors property.
Will only retrieve ancestors once, if property is already set, then nothing will be done. If there is not a parent post, or post ID and post parent ID are the same then nothing will be done.
The parameter is passed by reference, so nothing needs to be returned. The property will be updated and can be referenced after the function is complete. The post parent will be an ancestor and the parent of the post parent will be an ancestor. There will only be two ancestors at the most.
