Merge branch 'revert' into next

The tests with the 0.4.0-alpha.1 version showed that the approach using
mutable references to the Device in User, Admin and PasswordSafe causes
problems in nitrocli, see [0].  Therefore, these changes are reverted.

  Revert "Refactor User and Admin to use a mutable reference"
