    js: Account for promisified call() method
    
    A promisified method expects the callback parameter to be either
    a function (in which case the original method is called normally)
    or omitted altogether (in which case a Promise is returned).
    
    The call to open application details in Software does neither and
    passes null instead, which will result in a warning (because no
    function argument means a promise will be used, but not omitting
    the parameter means we end up with too many arguments).
