If we only remember the actions that added channels then we'd restore them when re-reading the gossip_store, so put a tombstone in there to remember to delete it. These will be cleared upon re-writing the store since the announcements wont be written anymore. Signed-off-by: Christian Decker <decker.christian@gmail.com>
