many failures in Win7 webgl2_conformance_tests

The failures aren't the same ones but started at exactly the same time.  Can file another bug if it turns out to be a coincidence.

It seems no other Win bot did anything like this at this time.

Darn it. It's my change https://codereview.chromium.org/2297673002 which still seems to have broken test expectations. Reverting and taking this.

Just a note that it was only the non-swarming configs that seemed to be affected.

It was all Windows machines as far as I can tell.

The revert https://codereview.chromium.org/2369373003/ should make these bots green again.

Re-landing this in https://codereview.chromium.org/2378543002 with expanded unit tests which catch the underlying test expectations bug.
