    Fix DTLS session resumption
    The session object on the client side is initially created during
    construction of the ClientHello. If the client is DTLS1.2 capable then it
    will store 1.2 as the version for the session. However if the server is only
    DTLS1.0 capable then when the ServerHello comes back the client switches to
    using DTLS1.0 from then on. However the session version does not get
    updated. Therefore when the client attempts to resume that session the
    server throws an alert because of an incorrect protocol version.
