Properties of nested objects aren't always serialized

[florianreinhart]

If a nested object has a property, which is also present in the parent, it is not serialized.

I've already created a test case.

'use strict'

const test = require('tap').test
const build = require('..')

test('nested objects with same properties', (t) => {
  t.plan(1)

  const schema = {
    title: 'nested objects with same propertie',
    type: 'object',
    properties: {
      stringProperty: {
        type: 'string'
      },
      objectProperty: {
        type: 'object',
        additionalProperties: true
      }
    }
  }
  const stringify = build(schema)

  try {
    const value = stringify({
      stringProperty: 'string1',
      objectProperty: {
        stringProperty: 'string2',
        numberProperty: 42
      }
    })
    t.is(value, '{"stringProperty":"string1","objectProperty":{"stringProperty":"string2","numberProperty":42}}')
  } catch (e) {
    t.fail()
  }
})

Expected result

{
  "stringProperty": "string1",
  "objectProperty": {
    "stringProperty": "string2",
    "numberProperty": 42
  }
}

Actual result

{
  "stringProperty": "string1",
  "objectProperty": {
    "numberProperty": 42
  }
}

very interesting! Would you like to send a PR as well?

I don't have time right now, but will look into it once I do. I'll let know when I start working on it.
