core (memory/sqlite): fixed v7 update performance issue: Performance issue was due to bad ordering in table dropping, this has been fixed. "infos" message are also deleted by this update as they are containing only presence data and take a lot of space for a barely useful data. A config option may be available in the future to store presence data in logs.
