Unable to iterate commits on all branches for a specific path (KeyNotFoundException)

[nickdurcholz]

When you attempt to use repository.QueryBy(string, CommitFilter) and specify all branches as the IncludeReachableFrom parameter, a KeyNotFound exception is thrown.

Reproduction steps

Add the following test to FileHistoryFixture to reproduce the issue

        [Fact]
        public void CanListChangesThatIncludeMultipleBranches()
        {
            var repoPath = CreateEmptyRepository();
            const string path1 = "Test1.txt";
            const string path2 = "Test2.txt";

            using (var repo = new Repository(repoPath))
            {
                // Make initial changes.
                var initial = MakeAndCommitChange(repo, repoPath, path1, "Hello World", "initial commit");
                MakeAndCommitChange(repo, repoPath, path2, "Goodbye world", "unrelated file change 1");
                var update1 = MakeAndCommitChange(repo, repoPath, path1, "Hello World!", "added punctuation");
                var branch = repo.CreateBranch("branch");
                Commands.Checkout(repo, branch);
                var branchUpdate = MakeAndCommitChange(repo, repoPath, path1, "Hello World again", "branch change");
                MakeAndCommitChange(repo, repoPath, path2, "Goodbye cruel world", "unrelated file change 2");
                Commands.Checkout(repo, repo.Branches["master"]);
                var update2 = MakeAndCommitChange(repo, repoPath, path1, "Hola Mundo", "switching to spanish");

                var commits = repo.Commits
                    .QueryBy(path1, new CommitFilter { IncludeReachableFrom = repo.Branches, SortBy = CommitSortStrategies.Topological})
                    .ToList();

                Assert.Equal(4, commits.Count);
                Assert.Equal(branchUpdate.Sha, commits[0].Commit.Sha);
                Assert.Equal(update2.Sha, commits[1].Commit.Sha);
                Assert.Equal(update1.Sha, commits[2].Commit.Sha);
                Assert.Equal(initial.Sha, commits[3].Commit.Sha);
            }
        }

Must have been fixed at some point because it works fine for me...
