Describe the bug
Set up/Tear down sections are not displayed in tests without suite

To Reproduce
Steps to reproduce the behavior:
1-2. Write simple test with t.WithTestSetup()/t.WithTestTeardown()

func TestSetupTeardown1(t *testing.T) {
	runner.Run(t, "My 1 test", func(t provider.T) {
		t.WithTestSetup(func(t provider.T) {
			t.WithNewStep("My 1 Step!", func(sCtx provider.StepCtx) {
				time.Sleep(1 * time.Second)
			})
		})
		t.WithNewStep("My 2 Step!", func(sCtx provider.StepCtx) {
			time.Sleep(1 * time.Second)
		})
		t.WithTestTeardown(func(t provider.T) {
			t.WithNewStep("My 3 Step!", func(sCtx provider.StepCtx) {
				time.Sleep(1 * time.Second)
			})
		})
	})
}

3. What has been expected: 't.WithTestSetup()/t.WithTestTeardown() sections are displayed in allure-report'
4. What you got actual: 't.WithTestSetup()/t.WithTestTeardown() sections are not displayed in allure-report'
5. Allure-Report screenshot (if any):
   

Expected behavior
t.WithTestSetup()/t.WithTestTeardown() sections are displayed in allure-report as in the tests with suites
