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.
