    GtkFileChooser: reveal selection after sorting view
    
    After clicking on any of the sort column headers,
    the view is properly resorted but the file we had
    selected can probably be now out of view due to
    the new sort order.
    
    This commit just makes sure to reveal the current
    file selection (if any) after the view has been
    sorted.
    
    Fixes #2683
