> If {{IgntieCompute.apply()}} is called on a client after reconnect, it fails. 
> Reproducer code is attached. The problem is that 
> {{RoundRobinLoadBalancingSpi}} (which is default one) is not notified about 
> topology reset.
> Sample stack trace:
> {code}
> class org.apache.ignite.IgniteException: Task topology does not have alive
