Custom validator not called on root schemas

[mihaispataru]

Hi,

i've come across an issue with the custom validator on root object schemas.

The custom validator is not handled when we create a root object schema.

const schemaRoot = {
  type: 'object',
  $$root: true,
  props: {
    prop1: { type: 'string', optional: true },
    prop2: { type: 'string', optional: true },
  },
  custom: (v, errors, schema, object) => {
    console.log(v, errors, schema, object);
    return v;
  }
};

The result when validating the schema is:

--------------------
ROOT object test
--------------------

Data: { prop1: '' }
Schema: {
  type: 'object',
  '$$root': true,
  props: {
    prop1: { type: 'string', optional: true },
    prop2: { type: 'string', optional: true }
  },
  custom: [Function: custom]
}
Validate Result: true

I've created a repl.it repository with test demo.
