heat-manage purge_deleted doesn't work

[Alli Ellis]

heat-manage purge_deleted doesn't seem to work.
After running purge_deleted an entry is still kept in the database and shown with list --deleted:

purge_deleted takes an "age" argument, it default to 90 days. Pass "0" to remove just deleted stacks.
