New perf dashboard erroneously clears zoom when poping history items

https://bugs.webkit.org/show_bug.cgi?id=141278

Reviewed by Chris Dumez.

The bug was caused by _sharedZoomChanged updating overviewSelection without updating mainPlotDomain.

Updating overviewSelection resulted in _overviewSelectionChanged, which observes changes to overviewSelection,
to schedule a call to propagateZoom, which in turn overrode "sharedZoom" we just parsed from the query string.

* public/v2/app.js:
(App.PaneController._overviewSelectionChanged): Don't schedule propagateZoom if the selected domain is already
shown in the main plot.
(App.PaneController._sharedZoomChanged): Set both overviewSelection and mainPlotDomain to avoid overriding
"sharedZoom" via propagateZoom inside _overviewSelectionChanged.
