For `haskell/test-framework`, HLS has mysterious errors showing up in VSCode

To reproduce:
```
gh repo clone haskell/test-framework
cd test-framework
gh pr checkout 75
haskell-language-server-9.10.1
```
This fails, while e.g. `cabal build all -w ghc-9.10.1` succeeds without error.

The `cabal.project` here has:
```
packages: ./core
./hunit
./quickcheck2
./example
```
However, there is also a directory `./quickcheck` containing legacy code for the deprecated package `test-framework-quickcheck`. This code is not functioning and should be ignored by a build process.

The first error by HLS is:
```

Perhaps you need to add `QuickCheck` to other-modules or exposed-modules.

```
HLS seems to leave the path to salvation here, by getting seduced to look into the broken package:
> No [cradle](https://github.com/mpickering/hie-bios#hie-bios) found for quickcheck/Test/Framework/Providers/QuickCheck.hs.
> Proceeding with [implicit cradle](https://hackage.haskell.org/package/implicit-hie).

From there the road to hell is paved:
> Loading the module
> '/Users/abel/bin/src/test-framework/quickcheck/Test/Framework/Providers/QuickCheck.hs' failed.
> It may not be listed in your .cabal file!

One wants to happily ignore this error, but it seems to derail HLS because we later see:
> Severity: DiagnosticSeverity_Error
> Message:
> attempting to use module ‘test-framework-0.8.2.1:Test.Framework.Utilities’
> (/Users/abel/bin/src/test-framework/core/src/Test/Framework/Utilities.hs) which is not loaded

This then causes a real type error:
> Severity: DiagnosticSeverity_Error
> Message: Variable not in scope: microsecondsToPicoseconds :: t0 -> Integer

Maybe HLS should not poke its nose into packages not listed in `cabal.project` or `stack.yaml`...
