fix for getParent function

which should return the last e tag, which is a type 1 event for social network.

wasn't doing the check for kind 1, previously which has been fixed now, precipitated by event c185bb5473912f2ad74d7d0d25464af0ddeaab0261af32d4de66709b99928ac0

which refers to a kind 42 event at end, which was being taken as parent id.
