App crashes in debug mode after a reload of the app

[shercoder]

Is this a support request?
No

Describe the bug
Since LaunchDarklyReactNativeClient.swift inherits from RCTEventEmitter and somehow LD is synthesizing the bridge property somewhere that I can't find. On reload, this property is nil, hence causes the crash when it attempts to sendEvent while trying to register a listener

To reproduce

1. Write code to register a listener in one of your screens that is launched as one of the first screens after opening the app.
2. Build and run the app (The app should run fine)
3. Open RN Developer Menu by shaking the device and hit Reload or CMD+R
4. Result: app crash

Expected behavior
The app should not crash on reload. It should successfully register the listener once it has the bridge.
