commit 992096665110674e8e9bc5be6e91c5b78249266e
Author: David Faure <faure@kde.org>

New cleanup in "akonadictl fsck": clean up orphan resources from the DB
The only way this can ever happen is when hacking agentsrc and removing
resources from it (or removing the whole ~/.config). But then you get
dead collection trees in kmail, always red, always unusable, and this is
the only way to clean this up.
