1.0.3dev: Fixed //New Ticket// navigation item is not highlighted when the `default_handler` is `TicketModule`. Refs #8791.

The active navigation item from the ticket module will now default to the newticket case, since it's the case that is handled in process_request when there isn't an explicit id.
