it seems that RCTDeviceEventEmitter interface changed in new react-native versions?

in 4.0.0-beta.9 RCTDeviceEventEmitter is imported from

import com.facebook.react.bridge.ReactContext.RCTDeviceEventEmitter

and in the last stable version 3.9.1 it comes from

import com.facebook.react.modules.core.DeviceEventManagerModule.RCTDeviceEventEmitter

[rodgomesc]

while we discuss a better approach for this if someone is using rn 0.71.x like me this monkey patch should work
