using hook that require getApp()

[deng232]

I'm currently using useDocuemnt() hooks from https://github.com/CSFrequency/react-firebase-hooks/tree/master/firestore#usedocument

can't call getApp() in function body cause it will cause FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created ( with initAuth() already called in the _app.js), and can't using useDocuemnt() in useEffect also.

I solve it by adding whenUnauthedBeforeInit: AuthAction.SHOW_LOADER(I did not setup loadercomponent), in the withAuthUser options. The getApp() now works without being in useEffect() or any callBack(). I'm don't know why.
