Allure-mocha does not show nested suites

[just-boris]

I'm submitting a ...

• bug report
• feature request (some people may consider it a regression, it worked better in 1.x)
• support request => Please do not submit support request here, see note at the top of this template.

What is the current behavior?

In the report you see all tests on the flat level, without nesting

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

desctibe('a suite', () => {
   describe('child suite', () => {
      it('test one', () => {});
   });
   it('test two', () => {});
});

What is the expected behavior?

At the suites tab, I expect the following

• a suite
  • child suite
    • test one
  • test two

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

Allure version	2.7.0
Test framework	mocha@latest
Allure adaptor	allure-mocha@latest
Generate report using	allure-jenkins@latest
