Nudge syncer thread when notifications are enabled.
Nudge syncer thread when notifications are enabled.

Several sync integration tests were failing because the fact that
notifications were enabled was not detected by the sync clients. This
changelist adds a call to NudgeSyncer() in OnNotificationStateChange()
so that the syncer thread is made aware of the fact that notifications
have been enabled. This change caused the integration test pass rate to
increase from ~20% to 90+%.
