Lyra don't creates nodes for multiple nested props

[mateonunez]

Describe the bug
With #17 Lyra implemented the support of nested properties. The implementation works fine if there is only 1 nested property in the schema. Adding more objects in the schema, the nodes are not inserted properly at the root level.

To Reproduce
Steps to reproduce the behavior:

1. Create a new Lyra project and paste the following code:

import { create, insert, search } from "@lyrasearch/lyra";

const lyra = create({
  schema: {
    email: 'string',
    name: { first: 'string', last: 'string' },
    login: { username: 'string', password: 'string' },
  },
})

insert(lyra, {
  email: 'one@two.three',
  name: { first: 'four', last: 'five' },
  login: { username: 'six', password: 'seven' },
})

const results = search(lyra, {
  term: 'six'
})

console.log(results)

Expected behavior
Everything looks good when searching for the values four and five, but the searching value belongs to the second block of nested properties (login), the results are empty.

Searching four as a term:

{
  hits: [
    {
      id: '70308384-5',
      email: 'one@two.three',
      name: [Object], // Found here
      login: [Object]
    }
  ],
  term: 'four'
}

Searching six as a term:

{ hits: [], term: 'six' }
