fix objc_resolve_class_links to actually rescan the unresolved list #57

It looks like this was the initial intent of 4ea82e1, but as implemented it would still only scan the unresolved class list once. Since unresolved_class_list represents the head and classes are pushed onto the head, any classes added to the resolution list after resolution started would be skipped.
