Fix collections and native app issue (dani-garcia#4685)

Collections were not visible in the organization view.
This was because the `flexibleCollections` was set to `true`

Found an issue with loading some old created Secure Notes which had `{}` or `{"type":null}` as there `data` value.
This isn't allowed. When detected, replace it with `{"type":0}`

Fixes dani-garcia#4682
Fixes dani-garcia#4590
