Lps 43399

Hugo, please review the commit at b17474ed0cb511667765340c075586165edddc80

Brian wants me to confirm with you.

Basically in LPS-32018 942f603baaa180fe96e034d64b77c221abb9ef05, it deprecated DLFolderLocalService.updateLastPostDate(), and copied its content to all places that needs this logic. This is really a strange change.

And now in LPS-43399. @laszlocsontos needs to async the DLFolder last post date update by @BufferedIncrement, which needs a service method to annotate. So he added another method which is basically doing the same thing as DLFolderLocalService.updateLastPostDate(), then have the deprecated one to call the new one which made this even stranger.

So I undeprecated DLFolderLocalService.updateLastPostDate() to prevent this new addition, if you can confirm there was no real reason that we need to deprecate that method in LPS-32018, please push up this to brian.

You don't have to review the rest commits.

Thanks
