Error in 'email' validator response.

[aezur]

When using the 'email' validator, the return value is getting garbled.

Instead of:

"error": {
    "message": "email has to be email type.",
    "invalidParameters": ['email']
  }

It returns:

"error": {
    "message": " email: qwe@qwe, has to be email type.",
    "invalidParameters": [
      {
        "error": "email: qwe@qwe, has to be email type."
      }
    ]
  }
