deploy_tester_contract() does not reveal the error message

[pirapira]

When deploy_tester_contract() causes a require() failure, deploy_tester_contract() raises an exception, but the exception does not contain the error message in require().

This issue keeps track of fixing deploy_tester_contract() so that it raises an exception with the error message.

[pirapira]

This is because contract.constructor().transact() does not fire an informative exception. Does anybody asking for that feature in web3.py?

[pirapira]

The documentation of Web3.py does not mention what happens when the transaction fails for some reasons https://web3py.readthedocs.io/en/stable/contracts.html#web3.contract.Contract.constructor.

It's not special because it's a constructor. I was just using transact() not call().

[pirapira]

Web3.py's ContractConstructor does not have call() method. It takes time to solve this one.
