Fix Don't show a warning if only one argument is passed to useNotify

[WiXSL]

This PR avoids throwing a warning if only a message is used in useNotify callback call, since everything else is optional.

const  notify = useNotify();

// Warning: This way of calling useNotify callback is deprecated. Please use the new syntax passing notify("[Your message]", { ...restOfArguments })
notify('Showing a simple message');
