emacs: fix a bug introduced by the recent search cleanups.

In commit 5d0883e the function notmuch-search-next-thread was changed.
In particular it only goes to the next message if there is a next
message. This breaks notmuch-show-archive-thread-then-next. Fix this
by going to the "next" message whenever we are on a current message.
