Since the node name randomization fix, we need to make sure that we
purge the old node with the same prefix and same IP from the nodes
database if it still present. This causes unnecessary reconnect
attempts.
Also added a change to avoid unnecessary update of local lamport time
and only do it of we are ready to do a push pull on a join. Join should
happen only when the node is bootstrapped or when trying to reconnect
with a failed node.
