Are these WK1 regressions, or are we just preserving existing behavior and that's hard to see in the patch?

I'd prefer to not have a default parameter so we don't accidentally omit the parameter when writing redirection code.

For WK1, we keep the previous behavior (no change to WebCore nor WebKitLegacy) which is to not follow any cross origin redirection.

There are 6 calls to startNetworkLoad so I would tend to prefer keeping it, but I can make the change.
If we are not using the right parameter, there will be crashes anyway since we are consuming sandbox extensions.

I'd still prefer to add explicit calls.
