Fix ASAN-reported heap-use-after-free bug.
ChatListModel used to notify Qt about its changed items via layoutChanged() signals. However, not only the layout changed but most times also the items and corrosponding QModelIndex objects and their internal pointers. After layout changed Qt tried to access now invalid QModelIndex objects and their internal pointers pointed to freed memory. Test-Information: Checked via ASAN. The previously perfect reproducable report by joining a MUC from the bookmarks went away.
