* add comma * remove unused parameter
* streamline stream execution Currently, these spec changes introduce a new internal function named `ResolveFieldGenerator` that is suggested parallels `ResolveFieldValue`. This function is used during field execution such that if the stream directive is specified, it is called instead of `ResolveFieldValue`. The reference implementation, however, does not require any such function, simply utilizing the result of `ResolveFieldValue`. With incremental delivery, collections completed by `CompleteValue` should be explicitly iterated using a well-defined iterator, such that the iterator can be passed to `ExecuteStreamField`. But this does not require a new internal function to be specified/exposed. Moreover, introducing this function causes a mixing of concerns between the `ExecuteField` and `CompleteValue` algorithms; Currently, if stream is specified for a field, `ExecuteField` extracts the iterator and passes it to `CompleteValue`, while if stream is not specified, the `ExecuteField` passes the collection, i.e. the iterable, not the iterator. In the stream case, this shunts some of the logic checking the validity of resolution results into field execution. In fact, it exposes a specification "bug" => in the stream case, no checking is actually done that `ResolveFieldGenerator` returns an iterator! This change removes `ResolveFieldGenerator` and with it some complexity, and brings it in line with the reference implementation. The reference implementation contains some simplification of the algorithm for the synchronous iterator case (we don't have to preserve the iterator on the StreamRecord, because there will be no early close required and we don't have to set isCompletedIterator, beacuse we don't have to create a dummy payload for termination of the asynchronous stream), We could consider also removing these bits as well, as they are an implementation detail in terms of how our dispatcher is managing its iterators, but that should be left for another change. * run prettier
* fix whitespace * complete renaming of initialItems
* Add error handling for stream iterators * also add iterator error handling within CompleteValue * incorporate feedback

builds on #1052 and so the diff from that should be useful:
