obshashrange: do not search for affected stable range cache is unavailable

Before this changeset we where resetting in all cases, and then looking for
affected ranges. In addition is the stable range were not available, the
functions silently returned no ranges affected.

Now, do one or the other depending of the availability of the stable range
cache. In practice we always do a broad reset because the code detecting
affected changeset is currently buggy.
