Fix: NRefactoryResolver now resolves constructor definitions (before it was returning UnknownMethodResolveResult)

Please Daniel check if this is OK and also tell me if fixes like this are already useless because of the new NRefactory. (next thing I would like to fix are Find references to interface members).
