### Describe the feature request

When I did not initialize Amplify at the Application level,
AutoSessionTracker was behaving strangely.
This prevented sessions from being created and deleted properly.

After that, a new session was created every time we sent an event.
While trying to figure out what was causing this issue, I came across a suggestion in AnalyticsClient > createEvent.
In createEvent, if the session of sessionClient doesn't exist, we create a new Session and pass it over.
In this case, the newly created session is not stored in the sessionClient and seems to be created anew each time.
If this is not the intention, my suggestion would be to save the session to the sessionClient when it is newly created.
This would make the behavior a bit more understandable.
Thanks!
