Fixed a number of bugs found during QA

Fixed a bug where the "Block user" toggle wasn't correctly reflecting the current users state
Fixed a bug where the "Blocked banner" wasn't showing the "unblock this user" alert.
Fixed a bug where the "Blocked banner" wouldn't re-appear if you re-block a user after unblocking them.
Fixed a bug where the conversation screen unblocking logic wasn't actually unblocking the user.
Fixed a bug where some settings options were disabled in open groups because the code thought the user had left the group.
Fixed a bug where the settings button wouldn't appear after accepting a message request.
