Hot reloading of assets (e.g. yaml) doesn't work

[entropitor]

Do you want to request a feature or report a bug?
bug

What is the current behavior?
When adding a file extension (e.g. yml) to getAssetExts and using hot reloading, it's not processed by the babel transform (e.g. babel-plugin-convert-to-json), instead it tries to parse it as js

What is the expected behavior?
The hot reloading of the file transforms the file using the babel transform, just like on first loading the file

@entropitor: Thanks for reporting! This seems to be the same issue as facebook/react-native#7279

The fix has been included in React Native v0.49. Feel free to reopen this issue if you can still reproduce it on that version
