emacs: Don't open unread messages by default.

When searching for an individual message, (by message id, say), it's
really annoying to have the entire thread open just because the thread
was archived without ever having been read.

This means that the "unread" tag is a lot less special, and it really
just exists as a mild cue for the user.
