Ruby Loo 00c26e85ba Fix race condition in backfill_version_column() ... Fixes a race condition in backfill_version_column(). It was fetching the objects whose version==None. Then it did an update to set the value of those object versions. However, it is possible for one of the object versionss to have been updated after the fetch but before the update operation, in which case the update operation might set the version to be an older version.
