OpenZeppelin external tests failing with "InvalidArgumentsError: leading zero"

The OpenZeppelin external tests are failing with the error: `InvalidArgumentsError: leading zero` in tests involving ERC-7702.

See: https://app.circleci.com/pipelines/github/argotorg/solidity/41135/workflows/95766470-f2be-41fb-8f24-cb964472f7d0/jobs/1919109

```

Start by reviewing the failing CircleCI job and the ERC-7702 external-test stack trace, especially the deployment call in test/helpers/erc4337.js and the scenario in test/account/Account.behavior.js. Reproduce the failure and trace the source of “InvalidArgumentsError: leading zero”; done means the OpenZeppelin ERC-7702 external tests pass without that error.
