In AMQ Streams KafkaTopic is not create if the "spec:" is missing or indented under the "metadata:" section

Issue

apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaTopic
metadata:
  name: my-topic-empty
  labels:
    strimzi.io/cluster: my-cluster
  spec:
    partitions: 1
    replicas: 1
    config:
      retention.ms: 7200000
      segment.bytes: 1073741824

I have tested with "--dry-run=client" and "--dry-run=server" but both accept this YAML file. But when applying it, its accepted but the Kafka topic is never created because its invalid.
