Incorrect hover shown on case class definitions

[ckipp01]

I'm not sure if this is the same root issues as #482 but I've been noticing that in some files where it's just a case class defined in Scala that the hover in sourcegraph just show def productElementName(x$1: Int): String instead of the desired case class. You can see this here:

https://sourcegraph.com/github.com/ckipp01/mill-github-dependency-graph/-/blob/domain/src/io/kipp/github/dependency/graph/domain/Detector.scala?L10:18&popover=pinned

There are also times that the copy method is displayed instead of the actual case case definition like you see here:

https://sourcegraph.com/github.com/ckipp01/mill-github-dependency-graph/-/blob/domain/src/io/kipp/github/dependency/graph/domain/DependencySnapshot.scala?L16:18&popover=pinned

And finally at times I've seen it displayed as object as well like you can see here:

https://sourcegraph.com/github.com/ckipp01/mill-github-dependency-graph/-/blob/domain/src/io/kipp/github/dependency/graph/domain/Job.scala?L18:18&popover=pinned

I assume these are all the same root issues as #482 because these symbols are all defined in that file, albeit synthetics. And sometimes going back on the same symbol will show you a random one of the three above.

Closing as duplicate of #482

The workaround is to emit LSIF directly with scip-java index --output=dump.lsif instead of going through the SCIP->LSIF conversion. The underlying issue is sourcegraph/scip#52, which is to update the SCIP->LSIF conversion to handle more the scenario where multiple symbols are defined in the same location (example: Scala case classes)
