init.pp: remove useless exec with default title

Per the docs, the special value `default` sets default attribute
values for other resource bodies in the same expression. There are no
resources in this expression so it doesn't do anything. This was
probably intended to be a "legacy-style default, but the style guide
says to avoid these anyway.
