clay: fix failure to load apps

When you loaded an app with an error, then fixed the error, it would
create the main gall %mult subscription at a time in the past.  Then,
clay would never fill the subscription since it couldn't get the old %a
entries for the apps.

This fixes the issue in two ways:  first, don't subscribe in the past.
Second, if clay can't get the old versions, just fire the subscription
anyway.
