Fixed a subtle but major bug in reporting best design elements on the experiment page (and in the tsv analytics download) that existed at least since StatisticsCursor was introduced. In the default view a design element was only shown once - with its best pval across all ef-efvs. For that design element analytics with worse p-vals for either the 'winning' ef-efv or all the remaining ef-efvs were excluded from the results. The fix is to return best analytics for each design element-ef-efv combination, not just for each design element.
Fixed to show only unique design elements in bar/line plot - in the case when at least 2 out of top 3 design elements are the same.
