Sometimes in reshape points break into two points that both have half a handle

[fsih]

These two points have been dragged apart so you can see the issue

Needs repro on how this happens

Maybe this is paperjs/paper.js#1068?

This solves the problem with closed paths using relative coordinates that sometimes the last point is different from the start point, which then results in an extra point when reimporting the data.
