Speed up stopping the reconnect logic if we are at a safe place to cancel

If the connection has not established yet, we can cancel the
connection process when the reconnect logic is stopped instead
of waiting for the connection to fail. If we have already
finished connecting and started the handshake, we wait
for it to complete so we can try to disconnect cleanly
