        * gui/component/select-names/e-select-names.c (set_book,
        addressbook_model_set_uri): disconnect/keep track of search result
        signal id.
        (e_select_names_init): Keep track of various signals, particularly
        status signal.
        (e_select_names_dispose): disconnect from any signals that are
        still active.  Fixes crash for #38202.
