Auto-paging doesn't work in mutations.

[grokys]

Trying to use auto-paging in the select part of a mutation fails:

var mutation = new Mutation()
                .AddPullRequestReview(addReview)
                .Select(review => new PullRequestReviewModel
                {
                    Id = review.PullRequestReview.Id.Value,
                    Body = body,
                    CommitId = review.PullRequestReview.Commit.Oid,
                    Comments = review.PullRequestReview.Comments(100, null, null, null).AllPages().Select(comment => new CommentAdapter
                    {
                        Id = comment.Id.Value,
                        Author = new ActorModel
                        {
                            Login = comment.Author.Login,
                            AvatarUrl = comment.Author.AvatarUrl(null),
                        },
                        Body = comment.Body,
                        CommitSha = comment.Commit.Oid,
                        CreatedAt = comment.CreatedAt,
                        DiffHunk = comment.DiffHunk,
                        OriginalCommitId = comment.OriginalCommit.Oid,
                        OriginalPosition = comment.OriginalPosition,
                        Path = comment.Path,
                        Position = comment.Position,
                        ReplyTo = comment.ReplyTo.Id.Value,
                    }).ToList(),
                    State = (GitHub.Models.PullRequestReviewState)review.PullRequestReview.State,
                    Author = new ActorModel
                    {
                        Login = review.PullRequestReview.Author.Login,
                        AvatarUrl = review.PullRequestReview.Author.AvatarUrl(null),
                    },
                });
