Full sync is now fixed

Full sync was previously not really good, Sms were ordered by date DESC, then the last date was good and when multiple loop iterations occurs, only 1 iteration happened
SmsBuffer now owns LastMessageDate instead of AndroidSmsFetcher
Full sync is now owned by AsyncsmsSync instead of MainActivity
Last message date is more accurate and less error prone
