s4-repl: fall back to repsFrom if repsTo not set

Windows does not seem to be always setting up repsTo using
DsUpdateRefs(). For now we will fall back to using repsFrom if repsTo
is empty. This is almost certainly incorrect, but it does get
notification based replication working with both w2k3 and w2k8.
