fix: compute stored test address after setting the tx nonce on scripts

[elfedy]

What 💻

Compute and store test address after (optionally) updating the deployer nonce on scripts.

Why ✋

Closes #720
On instances where evm_opts.sender is the same as the CALLER constant (which is the default value, happening for example when no raw private key is sent when invoking script), the nonce of the deployer of the script is modified to prevent nonce mismatches between simulation and execution. In that case we need to compute the test address with that modified nonce, so that we correctly forward calls/creates involving it to the EVM.

Evidence 📷

Added test fails before the change and passes after. Also running scripts with --account --password now work as intended (previously, setUp and run were invoked on the zkEVM causing undefined behavior).

tbh I think #731 might make this unnecessary since we would never end up attempting to create the test/script contract in EraVM anymore, but nonetheless it's a fix for our existing issue
