/**
 * @author Ruben Bermudez
 * @version 1.0
 * Use this method to copy messages of any kind.
 * Service messages and invoice messages can't be copied.
 * A quiz poll can be copied only if the value of the field correct_option_id is known to the bot.
 * The method is analogous to the method forwardMessage, but the copied message doesn't have a link to the original message.
 * Returns the MessageId of the sent message on success.
