Problem: exported genesis state files couldn't init a new chain. code hash mismatch

**Describe the bug**

Testing with v0.7.0 archive inode
The exported genesis state has panic when starting a chain calling `InitGenesus`, got `panic("code don't match codeHash")`
it might relate to the ethermint recent patch [PR](https://github.com/evmos/ethermint/pull/1234). The code has been deleted in the evm code storage but the account codehash in the account keeper didn't change.

**Solution**
Suggestion by @yihuang
offline migration script to correct the evm account state
