No conversion is done inside Joi.array().items

[AdriVanHoudt]

Test case:

var email = [{ email:' adri@Gmail.com ' }];

var schema = Joi.array().items(
    Joi.object().keys({
        email: Joi.string().email().trim().required()
    }).required()
).required();

Joi.validate(email, schema, function (err, value) {
    console.log(err);
    console.log(value);
});

Output: { email: ' adri@Gmail.com ' }
Expected output: { email: 'adri@Gmail.com' }

This also happens with lowercase() and uppercase()
Forcing convert: true doesn't help
