Done.

Is this only called from tests? We should rename this NudgeSyncerForTest().

[nyquist, 2013/02/27 05:19:16]

No, this is in fact how we nudge the syncer from Java (for example through
remote invalidations).

[Andrew T Wilson (Slow), 2013/02/25 16:23:35]

Sigh, I never did get around to refactoring this to either require a non-empty
auth_token, or get rid of auth_token entirely (always request it from the UI
thread if needed).

[nyquist, 2013/02/27 05:19:16]

I could file a bug about it if you want? Or do you want me to do that in this
CL?

[Andrew T Wilson (Slow), 2013/02/27 12:02:35]

I don't think that it's a pressing issue. Feel free to log a bug if you like but
don't bother addressing in this CL.
