res_ari_events: Add module reference when a WebSocket is open.

Browse Source 
This change ensures that the module isn't unloaded when a
WebSocket is open. Previously it was possible to unload the
module manually or during shutdown which could cause a crash
when any active WebSockets were terminated.
