Include the anti-entropy log in the state that is being transfered.

Currently, a transferred state contains only the data of the WootEngine and TRE.

The first anti-entropy with all neighbours done by the peer that just received and imported a state from the network, will be answered by the members of the group with all the messages generated since that state was initially computed. This is redundant and causes unnecessary network load.

By including the anti-entropy log in the transferred state, a peer that imports a state will have all the messages generated inside that group.
