When a new juju txn runner is created, we make a very important check on if the
mongo instance supports sstxns, if that check fails due to an external issue,
then it is silently ignored and a critical decision is made to revert to cstxns.
This both removes the fallback behaviour and introduce an error return value
when creating a new juju txn runner.
