When we edit a list view and change page before the change has been
savec, the saving and page changing will be done concurrently thus
possibly causing an error if the page is changed before the saved is
finished: the save will try to modify the page that is no more
displayed.
In this change, the list view editable wait for the saving to be
finished before reloading its content.
note: for 9.0 up to saas-15
