Test for finding correct method for overriden native method of hidden native class.

Test for finding correct method for overriden native method of hidden native class.

I think the current implementation of $patchMethod has bugs that make it 'mostly work'.  It patches one step too high (either the object or the prototype of the subclass).  That is why I needed to add test#2 to exhibit the behaviour I thought I would see on the first test.
