Fixes JSXText Regression

[DavidArchibald]

Fixes #30. The first commit are the manual changes and then I pushed two more commits; one for the results of npm run build and the other for the changes npm made automatically when I ran npm install. I am not sure all of them need to be committed which is why they're separated.

As a side note, you might consider running an update on the dependencies to fix what's sitting at 150 vulnerabilities.
