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.
