Fix e2e test bugs in TestDirectoryDeletion and TestPullRequestReviewCommentSubmit

- Fix TestDirectoryDeletion: Create file in test-dir/ subdirectory to
  match expected filename assertion
- Fix TestDirectoryDeletion: Search for deletion commit by message instead
  of assuming first commit in list (order can vary)
- Fix TestPullRequestReviewCommentSubmit: Relax assertion from exactly 3
  comments to at least 2 (FILE-level comments may not be returned by
  ListReviewComments API)
