[evolution-data-server/gnome-2-30] Don't refetch message headers we already have.

[David Woodhouse <dwmw2 src gnome org>]

commit 91ad06035dc633f362ec87c0fd2d8e9621fa267d
Author: David Woodhouse <David Woodhouse intel com>

    Don't refetch message headers we already have.
    
    We were issuing a headers FETCH starting from the last known UID. But we
    already _had_ the headers for the last known UID. Start from $UID+1 instead.
    (cherry picked from commit 6df64040a866166d54cc35078f204ee60e474f36)
