Convert components/signin/c/b/* code to OnPrimaryAccountChanged()

Methods OnPrimaryAccountSet/Cleared and
OnUnconsentedPrimaryAccountChanged() are deprecated. So this cl changes
these calls to OnPrimaryAccountChanged().

There is a behavior change introduced with this cl for
AboutSigninInternals. Observers are now notified when the unconsented
primary account changes as well as when sync account changes.
