[gnome-music/wip/jfelder/open-audio-files: 15/16] window: Set the stack transition once it is populated

    window: Set the stack transition once it is populated
    
    The FilesView is always selected at launch because it is the first
    view added to the stack. However, the next commit will add support to
    open audio files at launch and the FilesView will be selected instead
    of the AlbumsView. This will result in a transition effect from the
    AlbumsView to the FilesView.
    By setting the stack transition property once the correct view is
    selected, this prevents this transition at launch.
