The package hash needs to be copied to the message array as it needs to be
handled over to the miner after the message (e.g. initial announcement message)
has been processed and handled.

For example, when the node is booting, the announcement will contain the node
id. The node id is required to assign the "mining reward" to the proper node
again. Because of this, the announcement message must be handled before the
hash is being handled over to the miner.
