transaction fields have incosistent names

[PawelPodkalicki]

Transaction send_one and send_many in get_messsage response have incosistent names.
Sender has fields node, user, sender_address.
Recipent has fields destination_node, destination_user, target_address.

Prefix destination_ and target_ should be unified. Please, also consider, if all data is needed - (node and user is redundant, if address is provided).
