Notify user of tx fail in boa call output

[bout3fiddy]

Not sure how to do this but this tx to create a contract failed: https://bscscan.com/tx/0x77967045c0b62986ad3cf8933c746dff0b448dbffb2e71b89869e64ff54d1012

but boa returned an address (when nothing was deployed).

so there needs to be some sort of a check to tell the user that the tx failed

eth_getTransactionReceipt returns a status (0/1) that we are not currently checking.

It's still weird that in your case eth_estimateGas returned the wrong amount.
