If a bridge does not have a fail mode set, it returns nothing, i.e.
empty string.
This causes a failure when doing the want vs have compare in plays
where the fail-mode is missing, as we compare "" vs None respectively.
If a bridge does not have external_ids, ovs-vsctl returns '{}'.
This causes issues on the current want vs have comparison in cases
where the play does not define external_ids, as the comparison
is None vs '{}'.
