This commit changes when the sweep pkscript is assigned in the construction of the justice transaction. Currently, the sweep pkscript is assigned when the task is bound to a session. However, we will moving to an assignment where a unique sweep pkscript is used per channel to prevent address inflation. Hence, this commit makes the sweep pkscript a state dependent variable, since it can be known at the time the channel id is assigned.
