Fix T45232: Cycles bake artifacts with transparent textures
The issue was caused by uninitialized ray used for composite and AO evaluation.
Can;t really think of "proper" ray configuration here, it's all a bit arbitrary
but think initializing the ray in a way so we look at the surface in a negative
normal direction is much better alternative to uninitialized ray.
Open for alternative suggestions tho.
