fix: flatlist not rendering in rntl repo

[pierrezimmermannbam]

Summary

Fixes #1449

Because of the babel plugin for class properties (see this comment on the react native repo), rendering a flatlist would result in an error. Removing the plugin fixes the error, although I'm not sure why because that plugin is included in babel/preset-env for versions > 7 so we should have it no matter what. It may be an issue with different versions of the plugin, I haven't really understood what was the exact problem, I've tried to look at the transpiled files using the babel cli but they look exactly the same

Test plan

I added a test case for rendering a flatlist and all tests are passing
