CCE in simple criteria query with StatelessSession due to cast to ReactiveSession

[gavinking]

ReactiveEntitySelectFetchInitializer casts to ReactiveSession instead of ReactiveQueryProducer.

This is pretty bad. We should audit other casts to ReactiveSession and make sure there are no other such bugs.

What was the failure with Maria about?

The test assumed the query returned the rows in a certain order, IIRC.
