fix(bootstrap) swap IP addresses of Uranus and Saturn

Mistake: Saturn referred to the NY node and vice versa.

Correction: Fittingly, Uranus is in NY and _S_aturn is _S_ingapore.

Once the Docker image is built, I'll have to reboot the testnet to rectify the
errors. Peers with old configs may experience errors upon bootstrap.

Sorry world.
