[Rodrigo Moya <rodrigo src gnome org>]

commit 64f0ac1372b1d5179647bbdd11d9bbf80a2224be
Author: Matthew Barnes <mbarnes redhat com>

    Use e_source_selector_get_source_by_path().
    
    Allows Evolution to not have to know the ESource column number in
    ESourceSelector tree models.  Backported from "account-mgmt" branch.
