Use default NetworkPacket copy constuctor and assignment operator

clazy was complaining that the class had copy constructor but no assignment operator, which is usually suspicious

This is a bit of behaviour change though, since now m_payloadTransferInfo is also copied, which before wasn't, not sure if this is actually a good or a bad thing
