Proposed change

Add flag to backup store to track backup wizard completion

Frontend currently checks if a password has been set to track completion of the backup wizard, unfortunately that means it's possible to create a new key, view it, print the pdf, but that key is in the end not used if the user doesn't complete the wizard.

By adding a wizard completion flag, this behavior can be fixed so a newly created password is immediately saved.

Sounds good.

Side note: Just a general note that we should never use a parameter as input to logic for a different thing than the parameter purpose. This is classic lazy design that always comes back and hurts us.
