fix: resolve setup --clean panic (#1882)

Do not use Config::default()

default() has empty plugins config and that does not work with the default layout.
Use Config::try_from() instead, since it already handles the clean flag.
Also, do not check the clean flag twice, it is already handled in Config::try_from.
