[ES Harmony Proxies] bugs in no-op forwarding proxy example

Hi,

In getOwnPropertyDescriptor and getPropertyDescriptor traps of the no-op
forwarding proxy example, the "desc.configurable = true" instruction
fails if desc is undefined (which happens when the property is undefined).
A "if(typeof(desc) === 'object')" beforehand saves the situation.

Just for the record, on the only implementation I know (FF4b10), there
is a bug if either of these method returns undefined :

Thanks for noticing. I had already fixed the same code in the "default
forwarding handler" wiki page, but forgot about the example code on the
proxies page. It's fixed now.
