[evolution] EMFolderSourceElement: Store UIDs instead of URIs.

[Matthew Barnes <mbarnes src gnome org>]

commit 805b4904bae9b8e5c1cec9a3ee1beaec2bb05529
Author: Matthew Barnes <mbarnes redhat com>
Date:   Tue May 31 13:28:22 2011 -0400

    EMFolderSourceElement: Store UIDs instead of URIs.
    
    For backward-compatibility we can still decode <uri> elements, but new
    source rules will store the account UID, which is easier to deal with.
