FinalizePausedKeepalive in handleStopAllKeepalives.

In the case that a keepalive is paused and handleStopAllKeepalives is
called, there is no KeepaliveInfo for the paused keepalive and so no
onError callback will be called. The autoKi will also be cleaned up so
no callback will ever called that notifies the keepalive is stopped.
