Broken in Sketch 45
Sketch 45 handily removes the [`replaceAllLayersWithLayers`](https://github.com/abynim/Sketch-Headers/commit/a4b61ea30023c7b97db467ca1189f5c6788b1cc2#diff-ccc395008bbb97c5fca92e34aa2b4450L249) method that [we need to be able to render](https://github.com/airbnb/react-sketchapp/blob/master/src/render.js#L18).

Would be real swell if anyone has time to dig into the new headers and see if there's something we can replace it with.
