Fix broken tests

[segfaultmedaddy]

This PR fixes all broken tests that are left in update-secp2561-depdency. And is complementary to #228.

Can someone check tests, they are failing because of ethereumjs-config-lint. However ethereumjs-config-lint was broken for me too and locally I was running test:node instead of test.

@vanesyan have you tried npm run lint:fix and committing any fixed files?

Edit: yep pulled your branch and that fixed it for me.

I'm getting the below error next, perhaps you can help resolve, I don't have much context on the changed tests in the PR:

@vanesyan Thanks so much for this!

Have taken these changes and added them to #228 in e2a389c, preserving you as the author.

Closing here.
