Improve the heuristic for choosing an Individual's alias
Improve the heuristic for choosing an Individual's alias

Change the heuristic to choose the first alias which isn't unset or empty,
and if possible to choose the first alias which isn't equal to the Persona's
display-id. If all the aliases are equal to display-ids, however, use one
of them in preference to having no alias at all.
