fix fast handshake trigger for static hosts (#265) 

We are currently triggering a fast handshake for static hosts right
inside HandshakeManager.AddVpnIP, but this can actually trigger before
we have generated the handshake packet to use. Instead, we should be
triggering right after we call ixHandshakeStage0 in getOrHandshake
(which generates the handshake packet)
