Once again the webkitpy.common.config.committers_unittest.CommittersTest.integration_test_* tests bite us:

```
[344/2617] webkitpy.common.config.committers_unittest.CommittersTest.integration_test_contributors_ada_chan failed:

It also seems we don't run the integration tests in either EWS or post-commit?
