html_tests measurement test is flaky

[jmesserly]

The error looks like:

     <td>209</td>
        <td class="unittest-error">ERROR</td>
        <td>Expectation: Measurement measurement is async but before setTimout 0. (DOM callback has errors) Caught [object ErrorEvent]</td>
     
It seems to fail more on the build bots that are running a virtual OS--perhaps because the machine is under load and fails to deliver the measurement frame event soon enough.

Apparently similar failure happens when this test is being run in Dartium (see, e.g. http://chromegw.corp.google.com/i/client.dash/builders/dartium-win-inc/builds/711/steps/annotated_steps/logs/stdio):

I am for now disabling the whole html/html_tests for Dartium.
