JSDATA try to fetch relations even when value of localKey is undefined

See original GitHub issue

Description

Steps to reproduce

Create relations inside record (for example article)

relations: {
  belongsTo: {
    author: {
      localField: 'author',
      localKey: 'author_id'
    }
  }
}

Fetch article:
```
Article.find(id, { with: ['author'] })
```
Issue: even when returned article.author_id is not defined, JSData tries to fetch author
