Test was failed becuase I didn't get governance item data when I called `WriteGovernanceState`. So I got nil pointer dereference. Gotta set those data before I call WriteGovernanceState.

> How about changing the title like below example? "Add a logic to delete Governance, StakingInfo data from DB" good suggestion I'll reflect :)

Yes, there was fix in both klaytn and klaytn-deploy repository. - https://github.com/klaytn/klaytn/pull/1572 - https://github.com/klaytn/klaytn-deploy/pull/5

@hyunsooda LGTM, but you need to rebase your branch from klaytn:dev in order to resolve linter issue.

Oh sorry I took a wrong look.

Can you leave the geth implementation PR link?

I'll handle this.

Since following PR is merged, close this issue.
