fix restoring editor session after having closed all tabs (bug #60051) * file-editor.cc (save_session): moved saving the current session into this new separate function; (check_closing): save the session if here, regardless number of tabs; (handle_tab_ready_to_close): and not here, which would never happen when no tab has to be closed on exit * file-editor.h: new function save_session
