Combine navigation stops on OS Settings Manage Other People page

Previously, there were navigation stops on each of 1) a user's picture
2) a user's name and 3) a user's email address. With this change, the
picture is skipped, and the email address is read as a description of
the name, removing unneccssary tab stops
