Project Member Reported by grt@chromium.org, Nov 27 2017

Issue description

From https://chromium-swarm.appspot.com/task?id=3a15eb28e7823210&refresh=10&show_raw=1:

03:05:49.686 22568 worker/2 http/tests/devtools/service-workers/service-worker-v8-cache.js crashed, (stderr lines):

This is leading to flaky webkit_layout_test failures; please fix as soon as possible.

tracing: fix a bug when no endpoint is given

When no trace endpoint is given to StopTracing, we don't reset
filtered_metadata_ which causes a DCHECK failure in the next StopTracing call.

I think this is fixed now. However, the bot is still flaky, which I suspect is due to another issue (no tracing controller DCHECKs in the logs).
