Subject: [PATCH] Set the request cookies property to an empty dict if cookie
 parsing fails

This commit reverses the bug introduced in commit 4a4d871, leaving an
undefined cookies property on failure to parse a request cookie.

The bug results in a 'NoneType is not iterable' error when calling
RequestHandler.get_cookie() after a cookie parsing exception.
