[sheriff] add scoped trace to LoadAllPdfsTests

There's a leak being detected by the Chromium OS ASan LSan bot
when loading the test pdf files. Adding tracing of the filenames
to see which one(s).

=================================================================
==3638==ERROR: LeakSanitizer: detected memory leaks

Seems like the leaks are coming from pdf/combobox_form.pdf? Most of the leaks seem to be from CSS or HTML.

It looks still flaky according to the flakiness dashboard. I'll disable the test tentatively.
