Fixed invalid "flow_last_seen" timestamp for the first packet.

 * After the first packet was processed, "flow_last_seen" was still 0.
   This behaviour is invalid as the first packet may contain l4 payload data e.g. for UDP
   and it also breaks nDPId json consistency "flow_first_seen" > 0, but "flow_last_seen" == 0.
 * JSON schema: set minimum timestamp value for Epoch timestamps to 24710 for flow_*_seen and
   1 for pcap packet ts. Those values are dependant on some manipulated pcap's in libnDPI/tests/pcap.
