modules_k/presence Fixed wrong cseq and wrong expires bugs
1. Wrong cseq bug: happened in subs_db_mode!= DB_ONLY when generating Notify with expires=0 that was not triggered by a received Subscribe
2. Problem with expires raported in Notify message. There was a static buffer used twice when building the extra headers for Notify leading to expires parameter value always having last digits '70' (the value of Max-Forwards).
