Projected SinkRecord was missing timestamp information from the original SinkRecord

Can one of the admins verify this patch?

I agree that this is a good change. My only question is whether it would be better to instead call the following?

record.newRecord(record.topic(), record.kafkaPartition(), 
                 currentKeySchema, projected.getKey(), 
                 currentValueSchema, projected.getValue(), 
                 record.timestamp())

This is the same, except the record's offset and typestamp type are retained automatically and thus don't have to be passed in.

Thanks @niksajakovljevic for the fix! It makes sense. I'll go ahead and merge it as is since we are close to the end of the release cycle and both versions are similar. @rhauch your comment is valid. Let's consolidate in one of the next iterations.
