Exception calling object as function: Module RCTDeviceEventEmitter is not a registered callable module #40

Hi, thank you for making this module. I've encountered an issue after compiling and launching my app. Here are some additional details.

"react": "^16.4.1",
"react-native": "^0.56.0",
"react-native-threads": "0.0.13"

worker.thread.js is in my root folder
I bundle it with the provided commands to assets/threads

The file is found and I am able to get a console log out of it. I have removed all code from the worker file, this is it:

import { self } from 'react-native-threads';
console.log('hello from worker');
console.log(self)

However, after the two console log lines, the app crashes and produces this error:

07-20 14:47:15.090 29399-29494/? I/ReactNativeJS: hello from worker
07-20 14:47:15.098 29399-29494/? I/ReactNativeJS: { onmessage: null, postMessage: [Function] }
07-20 14:47:15.107 29399-29494/? E/ReactNativeJNI: Got JS Exception: Exception calling object as function: Module RCTDeviceEventEmitter is not a registered callable module (calling emit) (:16)

I am not using postMessage or onmessage at all in the rest of my code, only registering the worker.

Everything works fine in dev mode, only release gets messed up after launching the app.

Would it be possible to point me in the right direction?
