docs: We have some updates that are applied to the backed since last sync run. However, those updates are not in the
  localDatasetClient yet (they will in after next sync run). But those updates are applied on the client already.
  This means when we compute the delta between the client records and the localDatasetClient, those changes will be reverted from the client.
  To avoid that, we loop through those updates and remove them both from the clientRecords and localDatasetClient.
  This way there will be no delta for those records and the client will keep there records.
