Fix flakiness in PopupMenu tests

Fix flakiness in PopupMenu tests

SitePerProcessBrowserTest.PopupMenuTest has some observed flakiness,
apparently due to raciness in element repositioning from the change of
layout size caused by calling RenderWidgetHostView::SetBounds.

The call isn't necessary for the test, so this CL removes it.
