we must run a query first before the next delete transaction, the
reason is that a mutation does not wait for the previous mutation
to finish completely with a commitTs from zero. If we run the
deletion directly, and the previous mutation has not received a
commitTs from zero yet, then the deletion will skip the link, and
essentially be treated as a no-op. As a result, when we query it
again following the reverse link, the link would still exist, and
the test would fail.
Running a query would make sure that the previous mutation for
creating the link has completed with a commitTs from zero, and the
subsequent deletion is done *AFTER* the link creation.
