AI Summary: The Ash Authentication framework's `mix igniter.install` command is not correctly using the `--accounts` flag to set the user and token modules. The issue is that while the documentation suggests the `--accounts` flag should automatically set the user and token modules based on the specified accounts module, it currently defaults to `MyApp.Accounts.User` and `MyApp.Accounts.Token` unless explicitly overridden with `-u` and `-t` flags. The task is to debug and fix this behavior so that the `--accounts` flag correctly sets the user and token modules.
