Fix T43099: Modifiers in edit mode might mess up materials

The issue was originall caused by 2e8ba17 by removing necessery call
GPU_enable_material(). It was probably removed because in some cases
material was enabled after calling setDrawOptions.

That wasn't always a case for edit mode.

This is absolutely to be included to 2.73
