curl plugins: Use configured URL for all poll cycles

After redirect received, Collectd send subsequent requests to new location. That is wrong - Collectd should use configured URL for all poll cycles, regardless of the responses received previously. Problem was caused by libcurl issue 1631. To avoid that we set request url in each poll cycle. Closes: collectd#2328
