Jump to source of testWidgets is not working when group name of test is a variable

## Steps to Reproduce
1. Write a testWidget inside a group with a variable as name
2. Run test and Click on jump source
```

// 'Avatar Page'
void main() {
var currentFolder = "currentFolder";
group(currentFolder, () {
test('Foo', () {});
test('Bar', () {});
testWidgets('Widget test', (WidgetTester tester) async {
await preSetValidPhotoUrl(tester);
});
....
```

Jump to source does nothing for "Widget test" but works for "Foo" and "Bar"

## Version info

I am already using this build https://github.com/flutter/flutter-intellij/pull/5486 but I still have this problem when group name is not a static string. (57.0.1.dev)
