Because in 8040b95e8c4abeab1ab9fe50826f92c52995a814 we removed a previous post migrate file, some people may not have had those original polymorphic bookmark columns removed, and the migration from this PR running will cause duplicate column errors. cf. https://meta.discourse.org/t/duplicatecolumn-and-multisite-migrate-failed/224480
