The CR of a topic returns wrong status after decreasing partitions

Issue

• When we decrease partitions of a topic, the CR returns wrong status.

  The status of the CR is "Ready"

  $oc get kafkatopic.kafka.strimzi.io/topictest -o yaml | yq r - 'status.conditions'
  - lastTransitionTime: "2020-04-22T15:19:48.882Z"
    status: "True"
    type: Ready
  

  However, in the "Entity operator" log, we see the following error:

  [2020-04-22 15:25:49,900] ERROR <opicOperator:1300> [oop-thread-0] Error reconciling KafkaTopic strimzi/topictest
  java.lang.Exception: Number of partitions cannot be decreased
