  Generator is not resumed after a throw completion with a promise arg

  AsyncGeneratorResumeNext:
  If completion.[[Type]] is throw, and generator.[[AsyncGeneratorState]] is
  "suspendedYield", generator is resumed and immediately and
  closes the generator and returns completion.

  AsyncGeneratorReject will not unwrap Promise values
