Update notes for submitted changes

* - The inconsistency in UVE is due to failure in UVE deletion upon generator disconnect.   In delrequest.lua, db # is not set before querying the UVE info from redis for deletion   and this causes the UVEs originated by the generator to remain in redis even after disconnection. - Added a nil check for ‘href’ attribute in decoded json message Closes-Bug: #1346176
