Title: Trend auto refresh bugfix in combination with BEAUtY or old archiver

Bugfix: BEAUtY and old archiver persist data periodically (e.g. ever 30 seconds). When data are requested by clients only the data that have been persisted is returned. Data that are still in the engine's buffer are not returned. This can cause the automatic refresh to repeatedly fetch data.
