c++/reflection: splicing null reflection

The compiler now detects and handles splicing of null reflections in C++ reflection.

When splicing a null reflection, the compiler was printing a note indicating that the lang_type was not supported. This patch detects the splicing of a null reflection, which is represented by unknown_type_node, and handles it appropriately. A new test case has been added to verify the fix.
