Fix junit and jest-stare output in wrong folder

[t1m0thyj]

What It Does

Typically the __tests__/__results__ directory is structured like the following for unit test results:

__tests__
 |- __results__
     |- unit
        |- coverage
        |- jest-stare
        |- junit.xml

This PR fixes jest-stare folder being duplicated and junit.xml file being at wrong level:

__tests__
 |- __results__
     |- jest-stare
     |- unit
        |- coverage
        |- jest-stare
     |- junit.xml

Thanks for fixing! 🙏

I didn't realize that the results where not passed to other reporters as expected

# Before
**  jest-stare --testResultsProcessor: wrote output report to __tests__/__results__/unit/jest-stare/index.html  **

# After
**  jest-stare --testResultsProcessor: wrote output report to __tests__/__results__/unit/jest-stare/index.html  **
**  jest-stare passed results to additional processor "jest-junit"      **
**  jest-stare passed results to additional processor "jest-html-reporter"      **
