The test was already here for this bot 6 lines above. This bot is now failing
with a "test triggered twice" exception.
(https://build.chromium.org/p/chromium.fyi/builders/ClangToTLinuxUBSanVptr%20t...)

To prevent mistakes like this, update these files by running
`testing/buildbot/manage.py --convert display_unittests` instead of doing it
manually.

I'll send you a fix reverting this chunk.
