Summary

A couple of fixes are needed for eth_getCode and eth_getStorageAt.

The issue is that, currently, these methods don't work well on recently deployed actors (they use the parent state).

Refer to linked issues for details.

Completion Criteria

• fix(api): eth_getCode and eth_getStorageAt operate on current tipset state filecoin-project/lotus#13274 backported
• fix(api): eth_getTransactionCount operate on current tipset state filecoin-project/lotus#13275 backported
• Manual testing done as outlined in those issues. Bonus points for an automated test, if possible. Ensure it's not flaky.
