    book-tree: update selected_link in dh_book_tree_select_uri()
    
    The DhBookTree::link-selected signal was not emitted in certain cases
    because the selected_link was not always updated.
    
    The selected_link is still needed, it was added in
    commit effcc0fd9a693e91f63b20fef4b6777cd3b9dd1d.
