dukglue adoptPuppy/showFriends example breaks for no-arg invocation

[tedneward]

When the showFriends() method of that example is invoked, it errors out with the following:

expected native object, got undefined

This appears to be the case for any registered native function.

Huh, that's weird. I'm busy right now but will try to take a look in a couple days.

Thanks, appreciate it; I've skimmed through the tests code and it appears this particular scenario isn't in there, so that could explain pretty easily how it regressed. If I understood duktape and dukglue better, I'd take a stab at fixing it, but I only got into both last week. Let me know if there's some way I can help, though; it's been a while since I did C++ professionally (using this for a side project), but I grok most of templates relatively well. (Or I used to, anyway....)
