Replace reywood:publish-composite by cottz:publish-relations

Since bug #431 is due to publish-composite I tried to fix this package
and propose a pull request but the code was difficult to refactor. I
decided to use @cottz package instead which handled DDP messages in
the correct order.

Fixes #431
