Add incremental notifications plugin settings database upgrade
Summary: When upgrading the app to the version with the new privacy options (D17126), the app will crash with some error about missing a table in the Notifications Plugin database. This patch adds the table in onUpgrade in a proper way.
Test Plan:
- Build current app from master
- Disable some apps in the Notifications plugin
- Apply this patch (as well as its dependency, D17126)
- The app should work, with your old settings, and now able to toggle privacy options!
