In `ref` mode, leave the `contentType` header unset. This would allow the message consumer to use the `spring.cloud.stream.bindings.output.contentType` property to set the desired type. 

For example `spring.cloud.stream.bindings.output.contentType=text/plain`.

Note: that this is a work around. A permanent fix should be made in the `core`'s `FileUtils.enhanceFlowForReadingMode` method instead.
For Ref mode, leave the contentType header unset
