Incorrect a condiction of redis HGet

[logicad]

I found that a condition is incorrect when redis HGet requested

	// HGET
	if len(args) == 0 {
		member := args[0]
		s, err := c.HGet(k, member).Result()
		if err != nil {
			return nil, err
		}
		return resource.NewString(s), nil
	}

It seems that len(args) == 1 should be correct.
