/// @assertion Stream errors
///   Returns a broadcast stream of uncaught errors from the isolate.
///   Each error is provided as an error event on the stream.
///   The actual error object and stackTraces will not necessarily be the same
/// object types as in the actual isolate, but they will always have the same
/// Object.toString result.
///   This stream is based on addErrorListener and removeErrorListener.
///
/// @description Check that errors stream is a broadcast stream.
