🧪 Remove ethers/web3 from most test functions + mock network

[dawsbot]

The tests should not have a runtime dependency on ethersjs nor web3.js. In-addition, we have a lot of network needs currently which are flaky:

1. Remove ethers from all test files
2. Remove web3 from all test files
3. Mock all network requests to return with the appropriate data an eth node would
4. Spy on the network request to ensure the incoming request is accurate.

You can see an example of ALL of this here
