bug: componentList filter

[scottnath]

In your using the api example, the result of this line:

const options = Array.from(arguments).pop();

Is a string which is the full path to my fractal instance. So, when it tries to use options.fn() in this line:
ret = ret + "<li>" + options.fn(component.toJSON()) + "</li>";
options.fn is undefined

is the example code still valid?
