[Bug]GetAllUsersByDomain

[wusphinx]

Describe the bug
I got nothing with GetAllUsersByDomain

To Reproduce
model.conf
policy.csv

package domain

import (
	"testing"

	"github.com/casbin/casbin/v2"
)

func TestDomain(t *testing.T) {
	e, err := casbin.NewEnforcer("model.conf", "policy.csv")
	if err != nil {
		t.FailNow()
	}

	users := e.GetAllUsersByDomain("domain2")
	t.Logf("users :%v", users)
}

Expected behavior
According to the configuration, at least admin should be in the returned results
