KAFKA-5380: Fix transient failure in KafkaConsumerTest, close consumers
In `KafkaConsumer#testChangingRegexSubscription`, keep metadata updated
with both topics since heartbeat thread may remove unsubscribed topic during
its metadata update, causing the assertion that matches join requests to fail.
Also close consumer in all tests since they leave behind heartbeat threads.
