issue: [[ https://linear.app/comm/issue/ENG-6424/delete-state-on-identity-login-logout-delete-account | ENG-6424 ]]
Login will be handled once it's implemented. It's being tracked in [[ https://linear.app/comm/issue/ENG-6598/handle-login-action | ENG-6598 ]]. In this diff I want to handle logout, delete account and register identity actions
I will remove logic from specific reducers in next diffs
I had to change the dafault state on web - I need the `navInfo` to be correct. This is how we do it on native. I don't think it's the best, but at least the data is of correct shape, and again - this is how we do it on native, so I think we can use this for now
