[Bug]: NPE in SessionService.getScheduleBackgroundRunIn

[maximkir-fl]

What happened?

An early crash occurred to our apps deployed with the recent OneSignal SDK.

The SDK init code is:

open class Application : Application() {
    override fun onCreate() {
        super.onCreate()
        OneSignal.initWithContext(this, getString(R.string.one_signal_app_id))
    }
}

Steps to reproduce?

Check the attached logs; it is pretty straightforward.

What did you expect to happen?

The app did not crash.

Is it possible to disable the session tracking feature altogether?
