    fix(tx): Fix cascading livelock caused by cancelling a transaction.

    Cancelling a transaction was causing a cascading livelock by waiting
    forever for a channel close that would never happen.  This would cause
    the transaction in-flight semaphore to permanently lose a token, which
    would in turn cause a mass cascade of semaphore wait timeouts the next
    time something requested an exclusive lock on the datastore.  Resolve
    the issue by not waiting on the transaction channel if the transaction
    is being cancelled.
