Pavel Yaskevich 8f73ff4b68 [CSGen] Add a null check to prevent using invalid superclass type ...

While generating constraints for `SuperRefExpr` generator has to figure out
a type of superclass associated with a current reference. Doing so might
produce an empty type (aka `Type()`) when resolution fails, so `getSuperType`
needs to check whether type is valid before attempting to wrap it into `MetatypeType`.
