    shell: Fix title bar when
    
    Before migrating to HdyHeaderBar, gtk_window_set_title was enough
    to set the title in the window and GtkHeaderBar because GTK internally
    synced both. That bevahiour does not occur with HdyHeaderBar, thus
    HdyHeaderBar was updating the title/subtitle only when the document
    and the filename were set, leaving the title in blank otherwise
    That is, when both title_header and subtitle were set, and did nothing
    otherwise.
    
    We now check than in any other situation, we fallback to the title,
    which would take a proper value if there is no document, or only we
    have its file name.
    
    Fixes #1583
