    Reset the headerbar title when switching to the details page
    
    When the initial page load takes a bit of time, e.g. when loading a
    flatpakref, we may not have all the information right away to show. This
    commit fixes this case to make sure we don't show a stray title from
    a previous details page run while the flatpakref is loading.
