Problems with findSingleAttributeList - queries and oneToMany relations

[AlexWagner]

Hi there.
I added some tests for findSingleAttributeList in Class TestQuerySingleAttribute.
Focus are queries on oneToMany relations (Query on customer, oneToMany-Field: orders.status)

some queries don't work as they produce invalid sql
some queries deliver wrong result

See PR in our fork: FOCONIS#68

I'd ask to focus on 1 thing / 1 failing test and generally include an assert on the expected SQL and for a case where the SQL is not what is expected put a comment in for what the invalid SQL produced is.

Can you pick one failing case and produce a PR for that?

I think we have resolved those now. I'll close this.
