used_memory и used_memory_human вырезались на символ длиннее нужного,
поэтому первая цифра терялась: 1024 превращалось в 24, а "1.34M" — в
".34M". Значение памяти Redis в /api/system-info и в self-тестах было
занижено на порядок.

- parseInfoSections(): разбор INFO по indexOf(':'), пропуск заголовков
  # и пустых строк, работа с любой секцией
- info(): добавлены redis_version и uptime_in_seconds (секция server),
  в том числе в ветках memory и ошибки — с null
