Fix NPE when account has no preferredEmail

The NPE is thrown by AutoValue when constructing Address, as email is
not marked as Nullable. We could add a null guard in sendImpl, but
instead we make sure that any account in rcptTo has a valid associated
email. Otherwise there is no point for them being in the set of
recipients.
