Support joi v16

There will still be issues with the fix when composing. Eg. for:

validate: {
    payload: {
        a: JoiNext.number(),
        b: JoiNext.array()
    })
}

So some care has to be taken to use a Joi object as the top-level option.

As explained here: hapijs/joi#2107 (comment).

Is this really part of @hapi/hapi@18.4.0, which was released before this change?
It is included in the changelog https://hapi.dev/resources/changelog/, but still published version at npm lists "@hapi/joi": "15.x.x" as dependency.

You have to wrap your top level object with Joi.object().

Thanks, but I am not even trying to use joi. I am having some weird issue with npx trying to run a package than bundled hapi. It fails with some filesystem move operation. This is where I saw joi installed in several places due to hapi requiring 15.x.x. So I just wondered was this supposed to be bumped in hapi 18.4.0.

[hueniverse]

It was not.
