:auto-category doesn't reflect updates in org-ql-view

I have the following entry in `org-ql-views`:

```emacs-lisp
'("Maybe" "maybe.org" (level 1)
:super-groups
((:auto-category)))
```

It groups top-level headings in `maybe.org` by categories.

When I update `CATEGORY` property of a heading in `org-mode` and refresh the view buffer using `org-ql-view-refresh`, the heading still remains in the previous category. This might be about cache expiration, but I haven't investigated the details. This is probably a bug.
