what will we do with previous records, will we ignore them?

[devyetii]

We have 20 authorizers on mainnet, each staked with 10000 ZCN so total of 200K ZCN. For now, the simplest fix is to deploy a temporary SC function in the artemis HF that fixes them in a single txn then remove this SC function in the following HF.

@dabasov please approve so I can implement it.
