Fixed that email import did not work

Email import did not work if thre contacts stored in the
same record number of two different EF_ADN. In this case
the UE needs to identify the correct EF_ADN to apply based
on the SFI specified in EF_EMAIL.

Also fixed few unreported bugs including importing emails
will fail if there are more than 254 contacts and emails.
