another failing test case with delegation and errors

[jonathanong]

specifically when you delegate after you try/catch

function* test() {
  yield* sec();
  try {
    yield* sec();
  } catch (err) {}
  yield* sec();
}

function* sec(err) {
  return yield undefined;
}

var gen = test();
console.log(gen.next())
console.log(gen.next())
console.log(gen.throw(new Error('lol')))
console.log(gen.next())

0.11:

{ value: undefined, done: false }
{ value: undefined, done: false }
{ value: undefined, done: false }
{ value: undefined, done: true }

regenerator:

{ value: undefined, done: false }
{ value: undefined, done: false }

Error: lol

seems to be rethrowing the caught error on the second delegation.

Good catch @jonathanong! The .throw method gets less attention than .next, so thanks for taking a special interest in making sure it behaves correctly.
