Completion window does not show type/information of highlighted item

• Bug description : When the popup for the completion window opens, no information about the currently highlighted selection is shown.

• Observed behaviour : No information about the currently highlighted selection is shown, as seen in the screenshot below:

The following error is shown in the developer console:

Cannot read property 'label' of null: TypeError: Cannot read property 'label' of null
    at asCompletionItem (~/.vscode/extensions/Vans.haskero-1.3.1/node_modules/vscode-languageclient/lib/protocolConverter.js:77:63)
    at process._tickCallback (internal/process/next_tick.js:103:7)

• Expected behaviour : Able to at least see the type of the selection.

• OS: linux

• Plugin (ghc, stack, intero and haskero) version and VSCode version used : GHC 8.0.2, Stack 1.5.0, Intero 0.1.20, Haskero 1.3.1, VSCode 1.15.0

• Steps to reproduce:

1. Open a Haskell source file

2. Type something to trigger a completion

Hi,

I can't reproduce the issue.

If you open the test project https://gitlab.com/vannnns/haskero/tree/master/test/sample-8.02 with the command code ., open the file app/Main.hs and start typing m and asking for autocompletion, does it works properly ?
