`cabal list` considers packages that should be ignored by active-repositories

**Describe the bug**

Using cabal config:

```
active-repositories:
, hackage.haskell.org -- contains redesigned-carnival-1.0.0.0
, localhost:override -- contains redesigned-carnival-0.2.0.0
```

`cabal build` correctly uses v0.2.0.0 from the `localhost` repository. But `cabal list` shows `1.0.0.0` as the *Default available version*:
```
sh-5.0$ cabal list redesigned-carnival
* redesigned-carnival
Synopsis: Package for dependency confusion
Default available version: 1.0.0.0
Installed versions: [ Not installed ]
License: PublicDomain
```

**Expected behavior**

`cabal list` should ignore packages according to the `active-repositories` configuration.
Specifically, in the example above should show `0.2.0.0` as the *Default available version*.

**System information**
