Fix multiple tarcaps support

[JakubFornadel]

Task Description

When downcasing from base to derived packet handlers, we need to differentiate between different tarcap versions...

  if (version_ = TARAXA_NET_VERSION) {
    auto status_packet_handler = packets_handlers_->getSpecificHandler<StatusPacketHandler>();
    status_packet_handler->sendStatus(node_id, true);
  } else {
    auto status_packet_handler = packets_handlers_->getSpecificHandler<v4::StatusPacketHandler>();
    status_packet_handler->sendStatus(node_id, true);
  }

Refactor this so we downcast to a common::StatusPacketHandler base class
