Extend notif lifetime if not anim activity launch

While ag/17110765 expanded the lifetime extension to account for the
intent launch animation, it failed to account for no launch animation,
which means that lifetime extension needs to continue until the end of
the synchronous method.

Test: 1. Install Notify.apk (go/notify-apk)
      2. In the Notify app: Check off Delayed 5000 and Auto Cancel
      3. Click "Add" and spam click "Update" (5-10 times should suffice)
      4. Lock device, go to lock screen (*not* AOD)
      5. Immediately tap the Notify notification when it gets posted
      Observe: no crashing
