Templates: MongoDB repository generated finders don't support a single return type, but don't warn

[rcodesmith]

MongoDB-based generated finders don't support specifying a single object return type, but no warning or validation error is given.

@PersonDto findPersonBy(Long id);

See Advanced Tutorial - Based on findByCondition

The generated code is trying to call setUseSingleResult() on the access object, which is declared in FindByConditionAccess2, butMongoDbFindByConditionAccessImpl implements FindByConditionAccess rather than FindByConditionAccess2, and doesn't include this method.

We should either support the the setUseSingleResult() method or give a validation error.

Can you please clarify what you mean by "give a validation error"?
