More info in CLI when "server restarted?"

[elharo]

I'm investigating a query that results in an IndexOutOfBoundsError causing the query to crash with this message:

Query is gone (server restarted?)

and that's it. In this case it would be helpful if the CLI offered more context such as the exception stack trace. Would need to be added in the Query class around this code:

        if (client.isClientError()) {
            errorChannel.println("Query is gone (server restarted?)");
            return false;
        }
