throwNextList property
When true, the next list call made with
cachePolicy: CachePolicy.networkOnly throws (rather than returning
a failed ChatResult), then resets to false. Lets tests exercise the
"an awaited call inside a flow threw" path — e.g. ChatUiAdapter.resync
reverting its debounce seal on an exception, not just on isFailure.
Implementation
bool throwNextList = false;
