Fix recursion of notify last address

[samuelmanzanera]

Description

Fix infinite recursion of last address notification.

Before, the notification was done by each storage nodes of each previous transactions as recursion.
Now, to avoid infinite loop and improve performances, the storage nodes of the transaction will trigger and elect the right unique nodes to be notified. (because they know all the transaction of the last chain)
