SplitSettingsSync will allow the user to opt-out of browser sync.
However, IdentityAccessor::GetPrimaryAccountInfo() assumes the user has
consented to browser sync. The supervised user feature isn't coupled
to browser sync consent.

Switch to using the "unconsented" primary account. On Chrome OS this
account always exists for the logged-in user account, whether or not
the user consented to browser sync. On Android, it is always equivalent
to the primary account.

See go/cros-sync-mock and go/cros-primary-account for details.
