Reduce subprocess verbosity on call, or invoke, error

[ca11ab1e]

Related to #117. Maybe reducing subprocess exception could be a first step until a better error reporting?

Before the patch:

Got BadRequest while trying to access https://alpha4.starknet.io/feeder_gateway/call_contract?blockNumber=null. Status code: 500; text: {"code": "StarknetErrorCode.UNINITIALIZED_CONTRACT", "message": "Contract with address 0x123 is not deployed."}.
Traceback (most recent call last):

    raise BadRequest(status_code=response.status, text=text)

Hey @ca11ab1e! Thanks for creating these PRs! Right now, we're focusing on getting v0.2.0 of Contracts for Cairo out, but we'll check these out as soon as we can :)

This is a great addition, thank you!

Good call including __execute__. This looks good to me!
