fix cookie/url order in w3af/plugins/grep/analyze_cookies.py output logs

This is a fix for fixing w3af/plugins/grep/analyze_cookies.py output logs.

* Before this change
```
[Sat 20 Sep 2014 01:02:19 PM IST] The URL: "session=.eJyrVipILC4uzy9KUbKCMw2VdJRKi1OL8hJzU4HCMKahUi0AlpgQsQ.Bv7-Sg.o3DtbQ7jObRiXiLNRLMNNYyaDao; HttpOnly; Path=/" sent these cookies:
- http://localhost:5000/login
```

* After this change
```
[Sat 20 Sep 2014 01:14:08 PM IST] The cookie: "session=.eJyrVipILC4uzy9KUbKCMw2VdJRKi1OL8hJzU4HCMKahUi0AlpgQsQ.Bv8BDg.Ua3bb3cfweLBx2APn_LODwMV4_k; HttpOnly; Path=/" was sent by these URLs:
- http://localhost:5000/login
```

Note that the issue is *only* in the output logs of analyze_cookies.py plugin.
The information that appears in Results/KB Browser/analyze_cookies/Cookie info for the same test is totally correct, and, in fact, it is generated in other different function _collect_cookies() while this fix is in end() function.
