Why did we remove the "dumper-" prefix (and "trigger-" one below)? Those common prefixes tend to help me establish the mental models when trying to debug a new (to me) test.

ninjaedit: maybe we can do something similar to your sender change? testlib.NameForTest("dumper-", even.Name()) ?

I removed it because the names need to be created in advance, and if I then prefix it with "dumper-" it may exceed the 63 limit, plus I'm getting segmentation faults because eventTrackers then don't include the right matcher and it calls a function on nil object. Anyway, I'll see if we can improve it a bit.

Right now I'm facing a problem with running tests in parallel. Some of them label namespaces with knative-eventing-injection": "enabled" and some of them don't want this. These tests can't run in parallel. Pretty complicated...
