Comment 1 for bug 1413310

We will changed the secret chat db upgrade code to wipe the db instead of attempting a complex upgrade.

This problem is only visible to beta testers who have upgraded from the previous version of the app. Users after end of January would never see this. Nevertheless, to fix the solution for current users we will change the db upgrade code, and the data will be re-fetched from the server (as it is always available there, minus secret chats - which we haven't had before, so that's fine).
