Fix to-do assign to me link

When assigning an unassigned to-do to myself, there is no “assign to me” link. There is only an “Add assignee” link. Now I need to click on it, type my partial name and select. Why is there no “Assign to me” link? There is everywhere else in the product including the first time I create the TO-DO. Which is Ironic because you assign it bu default to the creator with out using the link. What is that link for then?
