emacs: Make notmuch-show-next-thread return nil on failure

Having notmuch-show-next-thread return non-nil on success and nil on
failure makes it easier for users to interact with notmuch via elisp.

This commit changes notmuch-search-show-thread too since the return
value of notmuch-show-next-thread depends on notmuch-search-show-thread.

Amended by db: fix whitespace in T450-emacs-show
