Studio crashing on startup

After patch https://codereview.qt-project.org/#/c/229131/ Studio crashes on startup on my Windows PC when opening some presentations (e.g. rotating_cube.uip). Crash happens on both opening presentation from startup dialog recent files and opening from recent files menu. Not happening with all presentations e.g. CoffeeMaker.uip. Somehow presentation loading requires scene to be visible and making it visible at CMainFrame::OnNewPresentation() is too late.
