PR #1573 broke e2e tests when mycelo isn't used

[oneeman]

Expected Behavior

The e2e tests in celo monorepo should work whether they are configured to use mycelo or not.

Current Behavior

Since PR #1573, the tests no longer work when they aren't configured to do genesis generation using mycelo. I noticed this from their failing in an open RP of mine: celo-org/celo-monorepo#8291. I ran it locally and confirmed that this is because of #1573. What happens is the node errors out with:

Fatal: Failed to register the Ethereum service: no Registry Smart Contract deployed in genesis

Steps to Reproduce Behavior

Run any of the e2e tests in the monorepo without mycelo. You can do this by either checking out the branch from the PR mentioned above, or by yourself changing useMycelo: true to migrate: true in the test you want to run.
