Perf Dashboard v3 confuses better and worse on A/B task page

https://bugs.webkit.org/show_bug.cgi?id=155675
<rdar://problem/25208723>

Reviewed by Joseph Pecoraro.

The analysis results viewer on v3 UI sometimes treats regressions as progressions and vice versa when
the first set (i.e. set A) of the revisions used in an A/B testing never appears in the original graph,
and its latest commit time matches that of the second set, which appears in the original graph.

Because the analysis results viewer compares results in the increasing row number, this results in
B to be compared to A instead of A to be compared to B. Fixed the bug by preventing the wrong ordering
to occur in _buildRowsForPointsAndTestGroups by always inserting a root set A before B when B appears
and A doesn't appear in the original graph.

* public/v3/components/analysis-results-viewer.js:
(AnalysisResultsViewer.prototype._collectRootSetsInTestGroups): Remember the succeeding root set B
when creating an entry for root set A.
(AnalysisResultsViewer.prototype._buildRowsForPointsAndTestGroups): Fixed the bug. Also un-duplicated
the code to create a new row.
(AnalysisResultsViewer.RootSetInTestGroup): Now takes a succeeding root set. e.g. it's B for A and
undefined for B in A/B testing.
(AnalysisResultsViewer.RootSetInTestGroup.prototype.succeedingRootSet): Added.
* public/v3/components/time-series-chart.js:
(TimeSeriesChart.computeTimeGrid): Fixed the bug that we would end up showing 0 AM instead of dates
when both dates and months change.
