Send sourceQualifiedName to forked clients #3380

Affected version

3.6.0-M1

Bug description

The sourceQualifiedName was added but is not being sent for forked clients via Encode / Decode

other than that, I am currently having a issue where the getSourceQualifiedName is null when I debug using mvnDebug test, so maybe it's not using the RunListenerAdapter class? I have to investigate further as I am not very aware of how the tests are loaded and executed, maybe they are triggered different for my case and for JUnit5Xml30StatelessReporter.

@olamy after some debugging sessions I realised this only happens when forkCount is greater than zero, whenever I put my forkCount as zero the getSourceQualifiedName field comes as expected, otherwise it's just null. This seems to be an issue on Surefire side, I could not find the reason as it's tricky to debug. Do you think it could be some caching? Getting some old version of the JUnitProvider with more forks?
