Haskell Linter changes Working Directory, then fails

I have a project set up as follows:

```sh
MyProject (dir)
app (dir)
main.hs
MyProject.cabal
```

I execute vim from the root directory as follows: `vim app/main.hs`.

In this situation, the haskell linter executes a `cd` into the `app` directory, and then upon trying to execute cabal, fails to find the projects cabal file.
