Subject: [PATCH] Created function to delete Searchables when event is deleted

Added the function
delete_event_searchable

in events\model\events.py, which deletes the searchable for an event, and called that function in

get_together\views\events.py

in the delete_event function to delete the searchable for the event before deleting the event
