Avoid multiple calls to snipe-it
Phabricator creates xactions as previews when someone is editing the ticket through the comments section.
We do not want to trigger the asset creation/fetching in Snipe IT in theses cases, otherwise we will end up with duplicated actions in snipe IT when phab user closes the ticket through the comment section.
