Samuel Merritt 99305b9300 Fix probe tests from commit cf48e75
Commit cf48e75 changed the default account/container/object ports in a
lot of places, including the probetests. However, it didn't change
them in doc/saio/bin/remakerings, and since the probe tests must match
the rings, they started failing.

This commit just backs out the changes to the test/probe directory so
that remakerings and the probe tests match again.
