Edge Sampling Integrator broken in Warped Area Integrator branch?

[fknfilewalker]

I tried the test_two_triangles.py test case with the EdgeSamplingIntegrator in the experimental (warped area) branch but it failes super hard. Also the result is different (both fail) when using the original serialize_scene way vs the new serialize_scene_class way with the EdgeSamplingIntegrator. In the master branch everything is fine.

Any ideas why?
