I have a strange issue with `When()` and models using UUID as their pk.
I prepared example project here: https://github.com/dekoza/djanbug
The `example.views.myview` includes code ported from the app I'm currently
developing - I have several models using UUIDs as their PK and I need to
do some annotations an aggregations with some specific cases handled with
`Case()/When()` combo.
Even though the db is empty on the example, the view crashes that `'1' is
not a valid UUID.` and the only '1' is the one in `When()`
I've also encountered issues with `Count('*', distinct=True)` but right
now I'm trying to reproduce it on the example and will post another ticket
when I'm done.
