Is it intentional that we pass NULL here which ends up settings up feature_info
without any extensions?
While we do set the expectation for glGetString(GL_EXTENSIONS) to match the
extensions passed in the call above.

Changing this breaks two tests (but I haven't looked at why exactly yet):
GLES2DecoderManualInitTest.RenderbufferStorageMultisampleGLError
GLES2DecoderManualInitTest.GetCompressedTextureFormats

Yes, NULL for that parameter means "give me all extensions that are available"
so about at like 76 we set which extensions the OpenGL mock will say are
available where as this line is saying which ones we want to enable.

I think I confused myself here due to a typo I had somewhere else. I reverted
the change, it works now with passing NULL here as expected.
