`source-repository-package` versions show up as `user target` in error messages

**Describe the bug**

When I do `cabal build`, a dependency solver error message says:

```
rejecting: memory-0.18.0 (constraint from user target requires ==0.17.0)
```

But when I look in the project, no constraint for `memory` mentions `==0.17.0`.

**To Reproduce**

In https://github.com/yesodweb/wai/commit/b6bc2b6c5ab93a1fb629aaa70477ebf7f4959f1b:

```
$ cabal build warp-quic
Resolving dependencies...
Error: [Cabal-7107]
Could not resolve dependencies:

[__2] fail (backjumping, conflict set: memory, quic, warp-quic)
After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: quic, memory, warp-quic
```

**Expected behavior**

Cabal should say something like:

```
rejecting: memory-0.18.0 (constraint from source-repository-package in cabal.project requires ==0.17.0)
```

**System information**

Operating system: macOS 15.1 (24B83)

```
$ cabal --version
cabal-install version 3.12.1.0
compiled using version 3.12.1.0 of the Cabal library
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.10.1
