Scripting: fix redis.call() error reporting.
Scripting: fix redis.call() error reporting.

Arguments arity and arguments type error of redis.call() were not
reported correctly to Lua, so the command acted in this regard like
redis.pcall(), but just for two commands. Redis.call() should always
raise errors instead.
