Don't append channel to non-root posts

Problem: When publishing a root post, other clients give you the option
of adding a `channel` property, which is basically just a hashtag. We
show this at the end of the message, but since replies often copy the
`channel` property then it gets appended to every reply.

Solution: Only append the channel as a hashtag for root posts.
