.json() errors logs are now opt in

Changes

• function .json() no longer logs errors by default, you now have to opt in to log these errors.
  For example

  connection.select('stats').json(function or({error}) {
    console.error("Could not parse stats!", error)
    return { cpu_usage: '0.00%', memory: '0.00 MB', time: 0 }
  })
