Fix string.split returning an empty table if string starts with sepea…

…rator (#7827) Calling string.split(":A:B:C:D", ":") returns an empty array. This is due to first empty string not making repeat loop decreasing max_split which has a 0 value when reaching until. Changing max_splits default value from -1 to -2 fixes that issue.
