[#1708] Add <T, E> Map<T, List<E>> ResultQuery.fetchGroupsInto(Field<T>,

Browse Source 
Class<E>)

- Fixed test for those test configurations, that do not generate POJOs
- Added more regression tests (not just checking for getId(), but also
getTitle()). This will be important for optimisation tasks like #1808
