Remove seed nodes?

```
  config.seedNodes([
    '/dns4/seed1.pos.nimiq-testnet.com/tcp/8443/wss',
    '/dns4/seed2.pos.nimiq-testnet.com/tcp/8443/wss',
    '/dns4/seed3.pos.nimiq-testnet.com/tcp/8443/wss',
    '/dns4/seed4.pos.nimiq-testnet.com/tcp/8443/wss',
  ])

```

NOt sure if this is the best. Maybe move them to comments?
