[Bug]: uncategorized transactions not included in "split: category" reports when "show uncategorized" option is checked

### Verified issue does not already exist?

- [X] I have searched and found no existing issue
- [X] I will be providing steps how to reproduce the bug (in most cases this will also mean uploading a demo budget file)

### What happened?

In a report with "split" type "category", uncategorized transactions don't show up when the "show uncategorized" option is checked.

I'm on 24.7.0 because of
- #3199

I checked the [24.8.0 release notes](https://actualbudget.org/blog/release-24.8.0/) and didn't see anything that obviously relates to this. Apologies if it's already fixed in 24.8.0.
