Fix an issue with a stale editor reference in shape utils (#2295)

Fixes an issue where the editor reference in shape utils was not up to
date with the editor returned from `useEditor`. Actually, the whole util
was the incorrect one and was holding a reference to the previous
instantiation of the editor.

This only occurred in dev mode, but could also happen in other cases
where editor is created multiple times. To see the kinds of issues this
causes in dev mode you can do the following:
1. Create an image, crop it.
2. Refresh the page.
3. Select the image, then double click it to enter crop mode.
4. You will not see the cropped area of the image. You need to change
the crop slightly and then it suddenly appears. This is because this
changes props, which reruns the memoized function.
