+summaryReporter: Add missing `cachedLogger.logBufferedMessages()` call in onTestRunFinished
+
+Since the move to buffered logging in https://github.com/modernweb-dev/web/commit/b2c857362d894a9eceb36516af84a800209f187b. A call to `cachedLogger.logBufferedMessages();` was missing. We fix this by adding it. We call `cachedLogger.logBufferedMessages();` after reportTestFileResults but before onTestRunFinished. So the logging we do in summaryReporter. onTestRunFinished gets missed.
+
+Fixes #2936
