Error when reading property of JSON that may be null.

[chrahunt]

While reviewing the comment here on #22, I came across a bug where we try to read the properties of a possible null value.

This can be recreated with the following on 2.12.0:

var validator = require('is-my-json-valid');

var validate = validator({
  "type": ["null", "object"],
  "properties": {
    "example": { "type": "string" }
  }
});

validate(null);

It seems that is-my-json-valid doesn't respect the type array, I have just run into this bug

This is a show stopper for us...any idea when this will be fixed?
