textDocument/references returns references only in the current file for Stack projects

`textDocument/references` method returns results for type references found only in the current file for a Stack project.

Given the following project structure:

```
app/
| Main.hs
src/
| Game/
| State.hs
package.yaml
Setup.hs
stack.yaml
example.cabal
```

And the State.hs content:

```hs
-- State.hs
module Game.State (GameState (..)) where

import Game.Core.Position (Position)

data GameState where
GameState :: {position :: Position, message :: String} -> GameState
```

GameState is used in the Main.hs as well.

Sending the textDocument/definition request to the LSP with the following params

```json
{
"textDocument": {
"uri": "file:///example/src/Game/State.hs"
},
"position": {
"line": 5,
"character": 7
},
"context": {
"includeDeclaration": true
}
}
```

Results in the following response
```json
[
{
"range": {
"end": {
"character": 11,
"line": 5
},
"start": {
"character": 2,
"line": 5
}
},
"uri": "file:///example/src/Game/State.hs"
},
{
"range": {
"end": {
"character": 24,
"line": 5
},
"start": {
"character": 16,
"line": 5
}
},
"uri": "file:///example/src/Game/State.hs"
},
{
"range": {
"end": {
"character": 45,
"line": 5
},
"start": {
"character": 38,
"line": 5
}
},
"uri": "file:///example/src/Game/State.hs"
}
]
```

Results for `example/src/app/Main.hs` are missing.

### Steps to reproduce

Send `textDocument/references` request for a data definition using GADTs.
