Restore SMS Messages with Titanium Restores then Deletes!
OK, here's the deal...

So, the issue was that Messenger vs Hangouts is controlled external to your application, and external to your google account manager, it's an OS-level setting.  So, the issue was I had to sign into messenger, agree to terms, declare it my default SMS manager, and then when I did the restore, it didn't automatically delete.  I guess prior to this, messenger and hangouts were in a fight somehow.

This is probably a one-off problem, I had not converted from the deprecated messenger to the supported Hangouts, my phone was kind of grandfathered in, while the default SMS program had changed.  

If you are in this situation in the future, set your default SMS to messenger, and hangouts won't delete your messages.
