Fixes the following error caught by Symfony's PHPUnit Bridge:
1x: Method "Psr\Http\Message\StreamInterface::getMetadata()" might add "mixed" as a native return type declaration in the future. Do the same in implementation "Http\Message\Encoding\FilteredStream" now to avoid errors or add an explicit @return annotation to suppress this message.
