pilot: avoid cancelling the tx subscription twice, use proper wg value 

In this commit we fix a newly introduce bug wherein we would close the
transaction subscription twice on shutdown. This would lead to a
shutdown, but an unclean one as it would panic due to closing a channel
twice.

We fix this my removing a defer statement such that, we’ll only cancel
the subscription once.
