Secure backup tweaks (#2277)

* Use a custom SDK build that might fix incomplete recovery state false positives. Enable chat backup by default

* Get rid of the chat backup feature flag

* Fix force unwrap warning

* Fix long line warning

* Prevent the recovery key confirmation banner popping up before the verification state is fetched. Stop showing secure backup user avatar and menu badges while the session is not verified.

* Switch back to the release version of the SDK

* Fix inconsistent session verification states, improve/simplify how to deal with it

* Fix unit tests

* Cleanup and hopefully simplify home screen banner presentations
