- Removes the skip from Bounties and CreateAccount.
- test:slow runs only the .slow. specs.
- Each step waits up to 20s instead of the 1s default, since it waits on a
live chain. The previous setting is restored when the file ends.
- assertDevNode fails a spec at once when no dev node answers. Without it the
api keeps reconnecting and the spec waits until the job's timeout.
