Fix QGraphicsView::scrollAfterResize autotest on Mac.

The auto-test was failing because it calculate the scrollbar indent
using style primitives. It's very fragile and doesn't work on MacOS
style (and may not work on other style too). Since we don't test style
stuff here, we can just apply the plastique style for this test.
