NullPointerException when destroying a stream

[ractive]

Destroying an undeployed stream fails:

dataflow:>stream create --name test --definition 'time | log'
Created new stream 'test'
dataflow:>stream destroy test
Command failed org.springframework.cloud.dataflow.rest.client.DataFlowClientException: NullPointerException
...

The stacktrace that leads to the NullPointerException:

java.lang.NullPointerException: null

The variable id that is returned from this.deploymentIdRepository.findOne(key) is null in StreamDeploymentController.undeployStream(StreamDefinition)
