F release results

Summary

Fixes SegFaults in the retrieve function (and others) which were caused by the too-early deletion of the transaction object by the garbage collector

Focus

The most relevant line is where we call caosdb_transaction_result_set_release_at instead of caosdb_transaction_result_set_at and release the entity from the result set.

Test Environment

Integration caosdb-juliainttest!7 (merged)
