A typo in pybullet.c

I think here, collisionShapeOrientationA should be collisionShapeOrientationAObj, though this is not mentioned in the documentation, I think it is still worth to correct it.

Good find, that is a copy/paste bug. The documentation still refers to collisionShapeOrientationA anyway, but the internal implementation should be collisionShapeOrientationAObj indeed.
