📚 Description

This change allows us to customize the E_ROW_NOT_FOUND error as it sticks the affected model into the error class

if (error.code === 'E_ROW_NOT_FOUND') {
  return ctx.response.send({
    'status': 400,
    'message': 'Failed. ' + error.model.name + ' Not Found.' // Something like this!
  })
}
