closing onosm.org note placed at Iran country node as an obvious cleanup

Note that there is an enormous pile of such notes placed there - and Iran has massive amount of onosm.org notes already.

This change was run as a cleanup of obviously mistaken actions and has not went through a bot approval. Let me know if it should be done.

There are many more onosm.org notes at that country node: so many that OSM API has problem to list all of them. But I will process them, there is no need to handle them manually.
