Michal Privoznik f7fee15ae8 event-test: Unregister close callback
When registering a close callback, the connection refcount is increased
as the connection object is passed to the callback and hence we must
prevent deleting it too soon. However, when closing the connection, the
connection object is just unrefed. So whenever a connection with a close
callback is closed, we end up with the connection object which has
exactly one reference. Leaving the code as-is doesn't mean the end of
the world as we know it, but why give a bad example?
