Fix createPath arguments not being passed down to Path constructor

[HriBB]

Description

I believe I have found a bug in paper.js. I am using javascript directly, so no PaperScript. My use case is the following:

// insertItems is turned off globally because I am using react-reconciler to handle rendering
paper.settings.insertItems = false;

// one of my tools has a use case, where I need to bypass react's rendering mechanism
var circle = new paper.Path.Circle({ insert: true });

// but circle is not inserted into the project and thus not visible until I render it with react
console.log(circle.isInserted()) // false

Path.Circle calls createEllipse, which calls createPath, which does not pass arguments to Path constructor.

Checklist

• New tests added or existing tests modified to cover all changes
• Code conforms with the JSHint rules (yarn run jshint passes)

I think we can simply pass on props, but will merge first and check after.
