fix(sessions): Finalize previous session even when auto session tracking is disabled

[romtsn]

Summary

• Removed isEnableAutoSessionTracking() early-return guards from PreviousSessionFinalizer, MovePreviousSession, and InternalSentrySdk.deleteCurrentSessionFile
• The flag controls automatic session lifecycle, not whether sessions exist — manually started sessions (via Sentry.startSession()) write the same files to disk and need the same finalization
• Updated tests to verify sessions are finalized regardless of the auto-tracking flag

Test plan

• Existing tests pass with updated assertions
• Manual verification: start a session with Sentry.startSession() while enableAutoSessionTracking = false, kill the app, relaunch — previous session should be finalized

Fixes #5108
