[CircleCI] Build walletkit explicitly & fix test (ethereum#411)

* [CircleCI]Build walletkit explicitly

Earlier, `yarn` would build walletkit in the post install step.
That has been removed in celo-monorepo, therefore, build walletkit
explicitly to avoid https://circleci.com/gh/celo-org/celo-blockchain/7304

* Fixes node URL tests

Broken due to error message formatting
