Extracting remote file stream.uri causing TikaException

[dragos-dumi]

When trying to extract a file via update/extract, the built in Tika from Solr returns this error.

When using stream.url, the request is not sending any header (as in the file method with form-data) but it's still using method POST method without any post data and that's what causing that Tika error. Since we are sending only parameters when using stream.url, we can use GET method (#475 )

if (preg_match('/^(http|https):\/\/(.+)/i', $file)) {
            $request->addParam('stream.url', $file);
        } elseif (is_readable($file)) {
            $request->setFileUpload($file);
            $request->addParam('resource.name', basename($query->getFile()));
            $request->addHeader('Content-Type: multipart/form-data');
        } else {
