Revert of Added test for non cached ETC1 (patchset #2 id:20001 of https://codereview.chromium.org/564493002/)

Reason for revert:
This is causing dm and gm to crash on the Win8 7770 bots, for example

http://108.170.220.120:10117/builders/Test-Win8-ShuttleA-HD7770-x86-Debug/builds/2128

An example stack trace looks like
