Wrong javadoc for deleteConnector method

[0xERR0R]

Javadoc was copy-pasted from resumeConnector,

see https://github.com/SourceLabOrg/kafka-connect-client/blob/master/src/main/java/org/sourcelab/kafka/connect/apiclient/KafkaConnectClient.java#L287

Thanks for the heads up. I'll include a patch to fix this in the next release.
