The `ganache.js` helper module uses `ganache-core` to start `ganache`
instead of `ganache-cli`, and allows all of the same customization.
Using `ganache` programmatically from our e2e tests is much faster, as
we don't have to wait that arbitrary 5 seconds before each test as we
wait for `ganache-cli` to start up.
