Bugfix: Socket Consumer Debug: Prevent PHP Warning: Undefined array key 1

[defunctl]

This prevents a PHP warning when using the Socket Consumer and have debugging enabled. It seems sometimes the response does not contain an HTTP status and just returns 1 as the body.

This is often paired with a PHP Warning of PHP message: PHP Warning: fwrite(): SSL: Connection timed out in /app/vendor/mixpanel/mixpanel-php/lib/ConsumerStrategies/SocketConsumer.php on line 215, but not always.
