     * items into 3 groups:
     * 1) Items that exist only in the snapshot. These items have been deleted, and
     *    should be moved to the list of deleted items. The creation time of these
     *    items is known, as they are stored in the database.
     * 2) Items that exist both in the snapshot and the backend. Since there's no
     *    change in the lifetime of these items, they do not need any special
     *    attention.
     * 3) Items that exist only in the backed. These items have been created recently,
     *    so their creation time needs to be fetched from the backend before they
     *    are added to snapshot we are storing to database during uninit(). We could
     *    retrieve creation times here, but because these items are usually accessed
     *    anyway during a session, we will just add them to a list of "fresh items"
     *    which will be checked whenever a contact is retrieved from backend.
     *    The creation times of all remaining "fresh" items which were not accessed
     *    during the session will be retrieved in uninit()
     *
     * After items have been analyzed, the in-memory snapshot will be identical to
     * backend. In-memory snapshot is updated whenever we add or delete items. In
     * the item analysis of uninit() we therefore have an up-to-date snapshot of the
     * contents of the backend. Changes that external application do the beckend
     * during the sync session will get discovered in the next session.
