[TM-256] Fix `InterpreterRes` propagation in `interpreterPure`

Description

Problem: when step constructs start it takes currentRes which contains all updates that happened before and all _irInterpretResults. Then statefulInterpreter may put something new there and eventually it gets concatenated with currentRes. After that currentRes contains about twice more elements (half of which are redundant).

Solution: it should pass empty updates and results to statefulInterpreter, because they are not used by statefulInterpreter. statefulInterpreter only adds something there.
