Label declaration/Validation

[adrien-candiotti]

Label declaration on Joi objects shadows the name of attributes that fails to be validated in the error message.

Example:

Joi.object({color: Joi.string().regex(/#[0-9a-fA-F]{6}/)}).label("test");

If I post a payload with a color field wrongly formatted I get:

{
  "statusCode": 400,
  "error": "Bad Request",
  "message": "child \"test\" fails because [\"test\" with value \"string\" fails to match the required pattern: /^[0-9A-Fa-f]{6}$/]",
  "validation": {
    "source": "payload",
    "keys": [
      "color"
    ]
  }
}

Thanks for the report, it's fixed and published.
