It appears the Thundermail Cloudfile provider does not get unregistered properly at start-up on debug builds. My guess is there's a race condition and this is appearing only on debug builds because they're slower.

Unregister the provider in add_setup and keep a providerRegistered listener
that removes it again if it reappears mid-run, restoring it on cleanup. This
keeps the known-provider-count assertions deterministic.
