 When set_role is called it doesn't check to see if the role is changing.
 So we can update the user and fire the set_user_role action even when
 nothing is changing.

 To reproduce go to the Users screen and "change" the role of an
 Administrator to an Administrator. Or use wp-admin/ms-sites.php to update
 options. The user will be updated and the set_user_role action fires.
