This works like a treat and I used it for import and export. Afterwards
I needed to adjust the component import/export test harness a lttle bit
so the call to "site.getSiteManager" would not blow up because the site
in those tests is a PersistentComponents instance itself.

Now I can use all functions in the ZMI, including snapshots, for a
PluggableAuthService.
