[evolution-data-server/gnome-2-30] Always enable QRESYNC where it's available.

[David Woodhouse <dwmw2 src gnome org>]

commit 2d4e5270786020b4c0e7afe2180c019b02ec57ff

    Always enable QRESYNC where it's available.
    
    This doesn't have much of an effect until we start using it, except for
    enabling the VANISHED response, and causing unsolicited fetches to have UIDs.
    (cherry picked from commit 9db64a5743863861611f25cdf32bd2705e4cdd4f)
