Issue with order in parameters in sendConferenceEmailInvitations() function

[JanKolo04]

I encountered issue with function sendConferenceEmailInvitations() in this function is wrong order with parameters because Required parameter is after Optional.

This function is in 226 line

Solution:

public function sendConferenceEmailInvitations($room_id, $params, $lang = 'en')
{
    return $this->sendRequest('POST', 'conferences/'.$room_id.'/invitation/email/'.$lang, $params);
}
