fix: issue where we would reset the fork to a problematic base fee

1: set gas price in CLI to default to 0 2: delete hack in code that is no longer necessary (at least I think it is no longer necessary??)

So i am referring to the set_code(0) part for impersonated contracts we were doing... we had to do that before but it seems we no longer need to? also it seems to cause problems... (one of many, unfortunately) 3: set self._fork_config.upstream_provider = upstream_name 4: delete the part in reset fork where we do self._make_request("anvil_setNextBlockBaseFeePerGas", [base_fee]) as that seems to cause problems and is no longer needed (again, is this actually no longer needed with this PR's changes?? because it just seems to cause problems otherwise that are fixed by deleting that code).
