Subject: [PATCH] ApiUpload: Fix fatal in dieStatusWithCode()

If $extraData was null, but $moreExtraData was given, the following
fatal would occur:

  Fatal error: Unsupported operand types in
  /var/www/html/w/includes/api/ApiUpload.php on line 408

Follow-up to c9b5b3e988e3554c231860a2da587dff16b05e0c.
