Start a session after init if AutoSessionTracking is enabled

[markushi]

Android-only, on top of that ensure that the LifecycleWatcher handles the existing session correctly.

📜 Description

Right now a session on Android is automatically created in via LifecycleWatcher at the onStart callback. If e.g. a crash happens beforehand, there is no session and thus it can't be marked as Crashed.

💡 Motivation and Context

Fixes #2241

💚 How did you test it?
