Fill 2 previous daily nonce on boostrap

[Neylix]

Description

Fixes an issue happening when an authorized node restart between a node_shared_secret transaction and it's application date (between xx:xx:40 and xx:xx:00 on dev / 23:55:00 and 00:00:00 on prod)
The implementation was filling the ets table with only the last node shared secret transaction, so after the node restart it cannot retrieve the daily nonce for the current day as it only filled the one of the next day

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Restart a node after a node shared secret and ask for a faucet, the transaction is now validated without error
