Fix TypeError when beforeEach throws

When an error was thrown in beforeEach (and probably before, after and afterEach
as well), Test.file is undefined and the following error is thrown by
mocha-report-sonar:

```

```

This was caused by the class name extracting calling path.relative with
undefined Test.file.

Here we protect extractClassName from doing so.
