Fix call to undefined method PhrictionDocumentTitleTransaction::renderHandleLink()

Summary:
`PhrictionDocumentTitleTransaction` calls `$this->renderHandleLink()`.
`PhabricatorApplicationTransaction` defines that method `public function renderHandleLink($phid)`.
PhrictionDocumentTitleTransaction extends PhrictionDocumentVersionTransaction extends PhrictionDocumentTransactionType extends PhabricatorModularTransactionType extends Phobject. No PhabricatorApplicationTransaction in that ancestor tree. Thus this call will fail.
Thus replace `renderHandleLink()` with `renderHandle()` which accepts a PHID as its parameter (credits to mainframe98 for finding out).

Test Plan: Unclear how to trigger via the UI, so run static code analysis and read/grep the code.
