In some cases viper doesn't interpret `section.value` as a subsection with `section` name, but value is value still can be accessed through full pathname. Fix `Config.Sub` method implementation in order to always interpret configuration like described above as a subsection. From now method never returns nil, therefore an additional check has been removed from the `Value` method. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
