The removal of the Profiler dependency on the TraceableEventDispatcher (#9170) allows to remerge the patch from #9068 that fixes #6686.

This PR also cleans up how profiles are stored. A Profile is now always stored only once.

The fix will only be available on 2.4+ as the changes are too deep to be backported to 2.2 and 2.3.
