Re-enable stress sync integration tests

Re-enable stress sync integration tests

The stress sync integration tests use 10 sync clients, and were
originally flaky due to testserver bugginess.

Several fixes have gone in since then, and it might be time to re-enable
those tests.

Note to future Chromium Sheriffs: If these stress tests do fail or time out in future, feel free to revert this patch.

This seems sketchy, but LGTM.  Just be sure to watch the buildbots closely after
this is committed.

These tests have been disabled for the past 6 months. Several testserver
infrastructure fixes have gone in since then, so I'd like to enable these tests
so we don't lose the coverage these tests offer us. I'll land this tomorrow
morning and keep an eye on the buildbots over the day.

Try job failure for 8568033-1 (retry) on win_rel for step "ui_tests".
It's a second try, previously, step "ui_tests" failed.
