Remove New Option

[stagfoo]

Hey,
I noticed you tried to remove the new option line in the convert.js
https://github.com/vacenz/last-draft/blob/master/src/utils/convert.js#L118

If you would I can look into changing this solution to not use the new Option

Sure sounds good, I had a problem trying to fix this when running npm run lint, as it broke the edit html. If you can fix it and get npm run lint to pass that would be great 👍
