only query draft trips in the dateRange

Up to this point, we have been querying all unprocessed/draft trips from pipelineRange start up to the endTs.
This unifies the start ts for both queries. (the end ts still differs because unprocessed trips could exist after the pipeline end, while processed trips will always be before pipeline end).

If for some reason there's an unprocessed trip older than the daterange start, it won't be included in the timeline anymore.
