gm: if test has no expectations, record its result as no-expectations regardless of ignoreFailure

After https://code.google.com/p/skia/source/detail?r=11640 ('Ignore any
pdf-poppler GM failures'), there are a bunch of pdf-poppler tests showing up
as failure-ignored at http://c128.i.corp.google.com/production-gm-diffs/latest/view.html

Make them go away.

I adjusted this self-test a bit: now, even if the test is marked as
ignore-failure, it still shows up in the no-comparison section of results if
appropriate.
