1. A recent refactoring of EthAccountWalletProvider's config from network_id to chain_id had a missed case in the constructor that was not updated.

2. EthAccountWalletProvider's chain_id was requesting a string, however the chain_id types defined elseware were int's

Why was this change implemented?

Without this fix, we are unable to instantiate a EthAccountWalletProvider following the example in the README.
