SharedID module: update tests to assert on behavior rather than logs (#7738)
SharedID module: update tests to assert on behavior rather than logs (#7738)

Update tests that fail spuriously: https://github.com/prebid/Prebid.js/issues/7355
I was not able to reproduce the failures, but in debugging I ruled out the possibility of module loading order and I believe the most likely culprit is other tests asynchronously calling `utils.logInfo` that sometimes happen in-between these tests' setup and assertions.

This may not be the real issue, but IMO testing log messages makes little sense anyway, so I updated them to test the actual SOT behavior.
