SIM Phonebook contact export/delete issues.

1. Currently, ATEL code does not support co-existence for both
type 1 and type 2 EMAIL/ANR file, so just return after parsing
type2 EMAIL/ANR.

2. ATEL would handle EMAIL/ANR record by checking if corresponding
EMAIL/ANR content is empty or NULL. But if mess data is present
in type2 EMAIL/ANR files, it will result in some wrong result.
So Add check whether mEmailFlags/mAnrFlags is set, if no, ATEL
will treat the record as unused.
