Handle multiple ReflectionAttribute subclasses in return type resolution

Instead of returning the first matching class name from the method's
return type, collect all matches and only use the result when there is
exactly one unambiguous match. When there are zero or multiple matching
ReflectionAttribute subclasses, fall back to the native ReflectionAttribute
class.
