noDefaults behaviour with any.empty()

[anthochamp]

Context

• node version: 6.5.0
• joi version: 10.2.0
• environment (node, browser): node
• used with (hapi, standalone, ...): standalone
• any other relevant information: -

What are you trying to achieve or the steps to reproduce ?

const schema = Joi.number().empty(5).default(5);

const res1 = Joi.validate({ Test: 5 }, { Test: schema }, { noDefaults: false });
const res2 = Joi.validate({ Test: 5 }, { Test: schema }, { noDefaults: true });

Which result you had ?

res1.Test === 5
res2.Test === 5

What did you expect ?

res1.Test === 5
res2.Test === undefined

Hello ! i'm able to it work by changing L450 of lib/any.js from :

else if (options.noDefaults) {
  finalValue = originalValue;
}

to:

else if (options.noDefaults) {
  finalValue = value;
}

not sure it didn't break something else in the process tho... ?
