Handle loginUserWithUserAttributes with only userId

[albinekb]

See https://community.intercom.com/mobile-sdks-24/react-native-crash-on-android-for-latest-version-5-0-0-4482

Since this commit, if you send loginUserWithUserAttributes({ userId }) you get a crash on android:

Thanks @albinekb 👍🏻

By any chance you'll fix below issue as well?

Failed to register user. We already have a registered user. If you are attempting to register a new user, call logout() before this. If you are attempting to register an identified user call: registerIdentifiedUser(Registration)

It spams our tracking error system
Since you closed issues on Github and don't react in https://community.intercom.com may be here will be some action

It happens only on Android and after we upgrade to v4

We noticed this only on iOS that there is a crash on initializing a user
