* Fix for issue 12526
Ensure that child isolates do not clear the dart_ui_state_ field present in the dart controller.
The commit dd1e0b59ec implemented code to reset the dart_ui_state_ back to null when an isolate was being shutdown to ensure there was no use after free issues when the main isolate exeutes Isolate.current.kill() it however it was also clearning the field when a child isolate was shutdown causing SEGVs later.
* Address code format issues.
