    mainwindow: Handle cancelling choosing a project to load with no fallback
    
    This fixes the scenario where you have no unsaved changes, Ctrl+O to choose
    a project to load, then cancel the file chooser and then try to import clips;
    it would fail because we didn't properly reset to a blank project instance.
