Fix DCHECKs in IdentityManager::GetPrimaryAccountInfo

On ChromeOS, IdentityManager::GetPrimaryAccountInfo DCHECKs that its
view of the primary account info matches the one in SigninManagerBase.
However, if the primary account's refresh token gets revoked, then the
account gets removed from the AccountTrackerService, and
SigninManagerBase will only remember the account's ID, but not the
full AccountInfo.
This CL updates the DCHECKs so that they only verify the account ID in
this case.
