What is the current behavior?

When I use --check-leaks flag, my tests fail.

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

It can be reproduced in the demo package. Add the --check-leaks flag here and see the output:

0 passing (102ms)
  2 failing

  1) Authorization
       "before each" hook:
     Error: global leaks detected: allure, cache


  2) Authorization
       Sergey Korol should be able to sign:
     Error: No executable!
      at MochaAllureInterface.get [as currentExecutable] (node_modules/mocha-allure2-reporter/src/MochaAllureInterface.ts:124:13)

What is the expected behavior?

Reporter should be compatible with any mocha option.

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

Please tell us about your environment:

Allure version	2.7.0
Test framework	mocha@5.2.0
Allure adaptor	allure-mocha@latest
Generate report using	n/a

The suggested solution would be to move away from globals in the API and use the import in every test that uses Allure runtime:

import allure from 'allure-mocha/runtime';

allure.step('Do something', () => console.log('Hi!'));

This is not only solves the mentioned issue, but makes the code more typescript-friendly.
