Fix a "withHasTransactions()" typo in AuditEditor

Summary: See <https://discourse.phabricator-community.org/t/typo-in-phabricatorauditeditor-php/1910>. This is trivial and reproduces easily, I just missed it in testing.

Test Plan:
  - Left a comment on a commit which I was the author of.
  - Before change: fatal with obvious typo.
  - After change: smooth sailing.
