KAFKA-3859: Fix describe group command to report valid status when group is
empty
With the new consumer, when all consumers of a consumer group are stopped
(i.e. the group is empty), the describe consumer group command returns
`Consumer group ... is rebalancing.`
This PR fixes this issue by distinguishing between when the consumer group
is actually rebalancing and when it has no active members.

> * I have a topic (1 partition) and a producer and new consumer that produce
> to and consumer from the topic.
> * The consumer belongs to group {{A}}.
> * I kill the consumer (whether it has consumed any messages or not does not
> seem to be relevant).
> * After a short period when group status is processed and finalized, I run
> the consumer-group describe command ({{kafka-consumer-groups.sh
> --bootstrap-server localhost:9092 --new-consumer --describe --group A}}).
> * The response I receive is {{Consumer group `A` is rebalancing.}}
> * I keep trying the command but the response does not change.
