The variant update endpoint returns a 200 with the updated content, but the docs says it should return a 204 with no Content

i've create a JIRA for it,  https://issues.jboss.org/browse/AGPUSH-1635


I think PUT's are suppose to be 204's, but there might be things relying on the fact that the update returns data,

here is a link to the AndroidVariants update endpoint,  https://github.com/aerogear/aerogear-unifiedpush-server/blob/master/jaxrs/src/main/java/org/jboss/aerogear/unifiedpush/rest/registry/applications/AndroidVariantEndpoint.java#L142
