[analyzer] Fix broken testcase (#75216)
When merging commit c873f77e87a9ebd02f94d6b9d46e84d43e1ceb38 I didn't
manually rebase it onto the tip of the main branch, so I didn't notice
that the testcase that's added by it needs to be tweaked to account for
the effects of commit 2f29ded4f98e8e1fa26725c618a08082a09b405a (which
was also merged by me a few days ago).
