PTAL!

I think I may have erred in my suggestion here :( I am very sorry. I preferred
the original patch. An even simpler implementation of all of this as per
crbug.com/393982 would be to expose a GetExtensionSyncData method on
ExtensionSyncService - make sure that knows to return the sync data for pending
extensions as well - then use that.

but that can be done in a cleanup.

Okay, no worries! :) I agree that the original approach via creation_flags is
the least evil atm.
I might have some spare cycles to help out with the cleanup, but I don't wanna
promise anything before we've finalized this quarter's OKRs.
