pms: Skip reinstall of prebundles correctly per user.

  If you created a new user after uninstalling a few prebundled apps,
  switched to the said user, and rebooted, you would have your uninstalled
  prebundles reinstalled unconditionally.

  This is due to peekPackageLPr's implementation of checking for package
  settings not being per user, while the checks for wasPrebundledPackageInstalledLPr
  and shouldPrebundledPackageBeInstalled are.

  Now, key off of whether any package settings exist,
  is currently installed for the user, and if it was
  ever installed before before attempting the parsing process.
