Sort xxx2Many with more records than client limit
The sort on a list view uses the search_filter to retrieve the list of ids but this method uses the default client limit to perform the query. If the xxx2many (which is not restricted by the client limit) has more records then this limit, the sorting can not be done properly because we will not receive all the ids sorted.
Indeed the screen should manage None as limit and we should set it for all xxx2Many screen.
