JAAS confusion

So just changing your client isn't going to fix the issue, as it is a
server side issue that is refusing to destroy the models.

https://bugs.launchpad.net/bugs/1714409

Is at least one of them that might be relevant for your issue.

I also know that we have:
 https://bugs.launchpad.net/bugs/1721786

which is a different iteration of remove-model failing (we changed a lot of
code to use a shared pool of information about models, and it has a
slightly different issue as models get removed). But that one is 2.3
specific and I expect it to be fixed by early next week.
