OpenID test XRI protocol improperly

The following returns true wherever "xri://" is defined in the identifier.

  // Strip the xri:// scheme from the identifier if present.
  if (stripos($identifier, 'xri://') !== FALSE) {
    $identifier = substr($identifier, 6);
  }

The !== FALSE needs to be replaced by === 0 as in:

  // Strip the xri:// scheme from the identifier if present.
  if (stripos($identifier, 'xri://') === 0) {
    $identifier = substr($identifier, 6);
  }

Thank you.
