Add AdvancedQueryForResultLookupDBIntegrationTest

Made in preparation of #378 and includes some more advanced queries (in terms of data/object arrangement).
```
{{#ask: [[SomeNumericPropertyToSingleSubject::1111]]
 |?SomeNumericPropertyToSingleSubject
}}
```
```
{{#ask: [[SomeNumericPropertyToDifferentSubject::9999]]
 |?SomeNumericPropertyToDifferentSubject
}}
```
Should be extended to cover conjunction, !=, and disjunction as well as a subquery.
Please split these methods, they are doing more than a bit to much, making it hard to see the high level concepts amidst the details.
