Use Ethereum provider from Safe Multisig Web UI #131
Description
Right now, even if the CPK runs as a Safe or standalone app, it requires an Ethereum provider (web3 or ethers) passed as a parameter in the EthAdapter constructor.
- This EthAdapter should only be needed if the CPK is running as a standalone app.
- If it runs as a standalone app it should use the Multisig Web interface provider.
