[Android] Fix RuntimeException in RNImmersiveModule
java.lang.RuntimeException: Tried to access a JS module before the React instance was fully set up. Calls to ReactContext#getJSModule should only happen once initialize() has been called on your native module. at com.facebook.react.bridge.ReactContext.getJSModule(ReactContext.java:102) at com.rnimmersive.RNImmersiveModule.emitImmersiveStateChangeEvent(RNImmersiveModule.java:74) at org.jitsi.meet.sdk.JitsiMeetView.onWindowFocusChanged(JitsiMeetView.java:504) at android.view.View.dispatchWindowFocusChanged(View.java:10257) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1193) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:1197) at android.view.ViewRootImpl$ViewRootHandler.handleMessage(ViewRootImpl.java:3602) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6119) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:886) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776)
