Bookmarks: fix name update after rename

The adapter update causing the ui update after a rename is triggered by the observer on the BookmarkModel dataset, by then the dataset has already changed, and the DiffUtilAdapter will compare the dataset and the new BookmarkList which are equal. To trigger the name update the adapter.update must be called before the BookmarkModel.refresh that actuates the dataset, when dataset and the new bookmark list are still different.

Closes #2177 (closed)
