Get rid of LOGGER.error in SimpleHttpFetcher

[kkrugler]

Currently we have:

            } else if (e.getCause() instanceof RedirectException) {
                LOGGER.error(e.getMessage());
                throw new RedirectFetchException(url, extractRedirectedUrl(url, localContext), RedirectExceptionReason.TOO_MANY_REDIRECTS);
            } else {

But we're throwing RedirectFetchException, so we shouldn't be logging anything. And the e.getMessage() call returns an empty string, so you get:

ERROR crawlercommons.fetcher.http.SimpleHttpFetcher                 - 

In the logs, which isn't very useful.
