Build nodes pick up tasks of excluded projects

I saw this the other day in one of our build nodes:

```
25.10.15 17:32:04 DEBUG [BuildersSupervisor]: Excluded packages in this node: ['dotnet9.0', 'dotnet8.0']
25.10.15 17:32:04 DEBUG [BuildersSupervisor]: nothing to process, sleeping for 10s
25.10.15 17:32:05 INFO [Builder-3]: processing the task:
id=330442 arch='aarch64' ref=TaskRef(url='https://git.almalinux.org/rpms/dotnet8.0.git', git_ref='imports/c9/dotnet8.0-8.0.121-1.el9_6', ref_type=2>
25.10.15 17:32:05 INFO [Builder-3]: building on the arm64-builder01.almalinux.org node
```

As you can see, the build node processed `dotnet8.0`, which should not have been picked up according to the list of excluded packages: `['dotnet9.0', 'dotnet8.0']`
