feat(execution-engine): change behaviour of fold over streams

Change behaviour of fold over streams to make it more similar to pi-calculus channels/names (for more info see ).

Closes .

BREAKING CHANGE:

The new stream behaviour is not compatible with old one, such as
```
(fold $stream iterator
   (seq
       (call ...)
       (next iterator)))
```
will never end after this change (for more info again see ).
