mod_admin_shell: Allow "*" as substitute for 'nil' for easier CLI usage Since prosodyctl shell with additional arguments assumes the first two are a section:command() and any following arguments are strings, passing a bare 'nil' is not possible. In order to avoid delving into this rabbit hole, instead produce a token that alone is not really a legal JID for use as wildcard.
