[gnome-builder/document-manager] GbDevhelpDocument: don't unref resulting DhLink from tree model

    GbDevhelpDocument: don't unref resulting DhLink from tree model
    
    The DhLink was not specified (perhaps improperly) as a boxed type. Therefore
    no reference was incurred during gtk_tree_model_get(). So there is no
    need for us to unref the structure.
