Remove timeout on send encrypted signature

Browse Source 
Bob was timing out if the encrypted signature could not be sent in 60
seconds. This behaviour is unnecessary because we are racing against
the cancel timelock anyway. By timing out before this, we remove the
opportunity for bob and alice to re-establish a connection.
