> [sync] Fix mechanism by which chromeos::UserManagerImpl observes ProfileSyncService
> 
> When a user signs in to Chrome OS, and NOTIFICATION_PROFILE_ADDED is
> fired, chromeos::UserManagerImpl::Observe() does not register itself as
> an observer of ProfileSyncService because the profile is not yet fully
> constructed, and therefore, the logged in profile is not identified as
> the default profile. This is due to a regression that was introduced in
> r176083.

> This is bad because UserManagerImpl fails to observe notifications from
> ProfileSyncService that are sent out as a result of auth errors. In
> fact, this was the root cause of bug http://crbug.com/234164.
> 
> This patch fixes the mechanism by which UserManagerImpl registers itself
> as an observer of ProfileSyncService, by responding to
> NOTIFICATION_LOGIN_USER_PROFILE_PREPARED, which is fired after the
> Profile is fully constructed, and the logged in profile is now the
> default profile, resulting in UserManagerImpl correctly registering
> itself as an observer of ProfileSyncService.
> 
> This patch also undoes the earlier fix landed with r206203.

> This is the true fix for http://crbug.com/234164.
