retransmit the diversification nonce in the packet carrying the SHLO

Browse Source 
The packet containing the SHLO is the only packet that is sent with
initial encryption. If it is lost, we need to make sure that the
diversification nonce is included in the PublicHeader, otherwise the
client will not be able to derive the keys for the forward-secure
encryption.
