webkitpy.w3c.test_exporter assumes all exceptions are HTTPError

[Sam Sneddon [:gsnedders]]

This is the second exception in bug 238735:

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Essentially, we seem to be assuming we always have a code attribute (which urllib.error.HTTPError has), but catching every exception.

Patch

This I think would fix it, but there's no easy way to test this currently, short of exporting something.

Let's just land this because from a basic review it's obvious that it shouldn't make anything worse.
