Fixed an issue in operator= when a class-specific REFLECTABLE().

Only the operator= was introduced from any reflection created using the REFLECTABLE(auto, ...) macros. If only a class-specific one was used (i.e. REFLECTION_REFLECTABLE_NONINTRUSIVE_ASSIGNMENT_OPERATOR(Foo, operator=)), then it wouldn't work.
