Pulling SRP from wrong repository

**Describe the bug**

I'm not sure how I triggered this, but I got the following after doing a major rebase of my current branch:
```
➜ cabal build all

remote: Counting objects: 100% (259/259), done.

```

with this cabal.project excerpt:
```
...

source-repository-package
type: git
location: https://github.com/IntersectMBO/cardano-base.git
tag: fb9b71f3bc33f8de673c6427736f09bf7972e81f
subdir:
cardano-crypto-class
--sha256: sha256-ExQ497FDYlmQyZaXOTddU+KraAUHnTAqPiyt055v0+M=
```

The output seems to indicate it tried to pull that reference from the project git repo, instead of from the one indicated in the SRP.

A `rm -rf dist-newstyle` and `cabal build all` succeeded in pulling the right git refs from the right repos.

**To Reproduce**

I don't have a reproducer yet.

**System information**
- Operating system: Windows 11 24H2, MSYS2 CLANG64
- `cabal` 3.12.1.0, `ghc` 9.6.6
