CQ flakiness due to broken assert in telemetry test script "timeline_based_page_test_unittest.py"

Project Member Reported by kmarshall@chromium.org, May 16 2017 
The telemetry unittest telemetry.web_perf.timeline_based_page_test_unittest.TimelineBasedPageTestTest.testFirstPaintMetricSmoke is breaking on unrelated CQ runs.

Trybot logs: https://build.chromium.org/p/tryserver.chromium.mac/builders/mac_chromium_rel_ng/builds/453925

Test stdout:

[518/541] telemetry.web_perf.timeline_based_page_test_unittest.TimelineBasedPageTestTest.testFirstPaintMetricSmoke failed unexpectedly 26.0458s:
  Chrome build location for mac_x86_64 not found. Browser will be run without Flash.
  Traceback (most recent call last):
    File "/b/swarm_slave/w/ir/third_party/catapult/telemetry/telemetry/web_perf/timeline_based_page_test_unittest.py", line 197, in testFirstPaintMetricSmoke
      self.assertGreater(v_ttfcp_max[0].value, 0)
  AssertionError: None not greater than 0

I think this is related to Ulan's work.
