When using reach, changing the label doesn't get applied, when an existing label is there

Context

• node version: v4.4.3
• joi version: ^9.0.0-0
• environment (node, browser): node
• used with (hapi, standalone, ...): standalone
• any other relevant information:

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

Describe your issue here, include schemas and inputs you are validating if needed.
When using reach, the new label is ignored.

const Joi = require('joi');
const schema = Joi.object({ foo: Joi.number().label('foo_1') });
const reachSchema = Joi.object({ 
   a: Joi.reach(schema, 'foo').label('foo_2')
});

console.log(reachSchema.validate({ a: 'blah' }).error);

Which result you had ?

Error: child "a" fails because ["foo_1" must be a number]
message: "\"foo_1\" must be a number"
path: "a"
type: "number.base"
name: "ValidationError"

What did you expect ?

message: "\"foo_2\" must be a number"
