Comments created with "Add a Comment" say "pending"

[alexr00]

1. Open a PR where you haven't started a review.
2. Add a comment using the commenting widget and the "Add a Comment" button.
3. The comment will add. ✅
4. A moment later, the comment will say "Pending". ❌

There are two things going on here:

1. When we add the comment, there is a quirk of GitHub that briefly makes the comment a "pending" comment. This is just part of the API and is expected. Once the review is submitted (there is a hidden review associated with single comments, this is also just the way it works), then the comment is no longer pending. We do properly submit the review; however these leads to the second thing that's going on...
2. After the review is submitted and the comment is no longer "pending" we should update the associated comment threads. We are not doing that and this is a bug.

So, in short, what should happen:

1. The comment is added and doesn't show "Pending".
2. A moment later, it does show "Pending".
3. A moment after that, "Pending" goes away again.
