[evolution] Clean up "ensure_sources" backend routines.

[Matthew Barnes <mbarnes src gnome org>]

commit 858a2a884dbc243c485f1424d90675e06fa207b2
Author: Matthew Barnes <mbarnes redhat com>
Date:   Wed Jun 9 06:56:27 2010 -0400

    Clean up "ensure_sources" backend routines.
    
    Remove redundant logic (we call e_source_list_ensure_group() and then
    proceed to do the same thing it just did), and use "local:" as the base
    URI for the "On This Computer" group.
    
    This requires commit 9e0845207b39f256f7e81d388741ed30a764ea7b in
    Evolution-Data-Server to work properly.
