 Description   

During chunk migration, versions are updated and then config.chunks is queried to try and return the latest version, including other simultaneous operations' updates to versions. This is not necessary since other operations may change the version while we are returning the version we have found, so we should avoid doing this extra work and return the version calculated from the migration.
