DynamicContractTests never run all tests

[koraykoska]

The DynamicContractTests always stop creating tests because of this line.

contract.deploy somehow always fails and because we just return there. We don't even notice when running the test suite.

I think the deploy fails because there is no constructor function in the ERC721.json stub.

@pixelmatrix How was this meant to be tested?

Hmm, that's a good catch! Looks like a simple mistake. Perhaps this was supposed to use another stub? I can submit a fix for this.
