real fix for Logic Bricks UI smart controller (#33746)
previous commit (54102) actually reintroduces an old bug where Blender sigfaults when
the sensor and controllers are not from the active object.

The real fix for report #33746 is to clear the "object" property after the operator ran.
I'm not sure why when I call the operator from command line the property is cleared, but not
when I called it from C. Either way all should be working now.
