[sync] Re-enable SyncErrorTest.XmppAuthErrorTest

The sync integration test SyncErrorTest.XmppAuthErrorTest was flaky on Mac due to typed_url_data_type_controller.cc not being able to access the history service.

It appears that recent changes have fixed the flakiness, and the test passes with large --gtest_repeat numbers. Enabling this once the trybots are satisfied.
