Send a PING frame at the start of QuartcPeer tests so that probing works.

Since QuartcPeer only sends datagram frames, it does not provide QUIC with any
retransmittable data to use for probes.  Sending a single PING frame at the
start of the connection (right after the handshake finishes) gives QUIC
something to retransmit for probing.
