Quite 'dirty' way to fix imports starting with multiple '../'.

Could we count the number of times ../ appears, and use that number times 3 where we have path[3:] etc? Would be cleaner and more robust, i.e., in case a path starts with ../../../../../.

I believe the Pytest tests are failing because your fork does not have the Etherscan API keys and RPC urls in its repo secrets. If you can add your own keys/urls in your fork, then when the tests are re-run they should pass.
