Unit test report feature does not display classname
### Summary
New unit report does not display the class name of failing test. So it's not easy to determine, which test is failing, especially if you have hundreds of tests.
### Steps to reproduce
Execute a failing maven surefire test, that is failing
### What is the current *bug* behavior?
The test class is missing. Only the test method is displayed
### What is the expected *correct* behavior?
(What you should see instead)
### Relevant logs and/or screenshots
