QUIC: set idle timer when sending an ack-eliciting packet. As per quic-transport-34: An endpoint also restarts its idle timer when sending an ack-eliciting packet if no other ack-eliciting packets have been sent since last receiving and processing a packet. Previously, the timer was set for any packet.
