non-provisioned devices are not redirected to Setup Wizard when going to /user/ routes

DeviceNotProvisioned at /en/user/
No exception message supplied

After starting the server with a new KOLIBRI_HOME I refreshed at /en/user and it did not redirect me to Setup Wizard as expected.

@rtibbles My hunch is that this might be because of some changes to the redirect hooks in core/views.py?

[rtibbles]

My guess would be that parallel changes in develop are causing errors in the middleware - will debug.

[rtibbles]

Oh... we deleted the middleware a while ago, and I think we were relying on root redirects to handle this, so I don't think this is new behaviour. It's just more egregious now, because the user page accesses device settings info in its plugin data, and gives this exception.

[rtibbles]

OK, so the issue here is that we were previously doing the redirect in the frontend, but because the user page now tries to access a device setting during its data bootstrapping, it blocks the page from loading and so the redirect doesn't happen.
