If extended class does not contain any decorators, serialize returns empty object

```
export class Company {
  @JsonName() companyName: string;

  constructor(data: TCompanyBase) {
    Object.assign(this, { ...data });
  }
}

export class CreateCompany extends Company {
  constructor(data: TCompanyBase) {
    super(data);
  }

  toServer(): object {
    return serialize(this);
  }
}
```

Call to toServer method will return empty object.
