patron search result order sorting

patron search result order sorting

The default patron search "order by" on the server side is last name, first
name, and actor.usr.id.

The staff client intended to request last name, first name, middle name, and
date of birth (when actor.usr.id to be tacked on in the middle layer), but a bug
prevented this.

This fixes that.
