SC: Worker should not be executed while replicating a transaction from self repair

[Neylix]

Describe the problem you discovered

During the replication of a transaction, if the transaction has a recipient, the storage node triggers the execution of the corresponding smart contract.
This works as expected while replicating a new transaction, but the execution should not be triggered if the replication comes from the self repair as it is a past transaction and the execution has already been done by other nodes.

Describe the solution you'd like

In the Replication module, we should pass the parameter self_repair? to the Contracts.load_transaction and do not execute smart contract if it comes from self repair.
