This differential implements new log to handle account deletion request. Firstly consistency of request and DB is checked against. If account deletion request does not have password then DB should have NULL value in hasn column and vice versa. Then if request is consistent with the DB,
request password validity is checked against only if hash column is not NULL. If request is not consistent with DB or DB hash does not match request password, error is thrown.

Create SIWE account, go to delete account panel, type any string in password input prompt and succesfully deletre account.
