TO does not handle renaming of generated CR

TO creates KafkaTopic resources named like this 

consumer-offsets---84e7a678d08f4bd226872e5cdd4eb527fadc1c6a

If the user wants to rename this CR, a few steps are needed to be done:

• disable the TO
• delete the old CR with the name ‘kafka-topic-name’+‘hash’
• create a CR with the name ‘kafka-topic-name’
• delete TO internal storage deleteall /strimzi
• enable the TO

There are some misbehaviors observed.

Before these steps, the TO log contains a message

ZkTopicsWatcher:153 - 6|/brokers/topics 3:+__consumer_offsets: Error responding to creation of topic __consumer_offsets
org.apache.kafka.common.errors.UnknownTopicOrPartitionException: 

After these steps, there are more suspicious messages. After 15 minutes even another KafkaTopic with the name 'topicname—hash' is created.
