Updating settings requires manual restart

Issue Description

When updating "editor.insertSpaces" in the following, the changes are not reflected immediately. In order for changes to take effect, I need to manually restart omnisharp.

settings.json:

"[csharp]": {
    "editor.defaultFormatter": "ms-dotnettools.csharp",
    "editor.detectIndentation": false,
    "editor.tabSize": 4,
    "editor.insertSpaces": true, <-- changing this to false is not reflected automatically
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,
    "editor.formatOnSave": true
  }

Steps to Reproduce

Open any .cs file and observe tab/space behavior
F1
Type & Click: "Preferences: Open Workspace Settings (JSON)
Insert snippet above
Toggle editor.insertSpaces from true to false

Expected Behavior

Toggling this setting should be reflected in real time, or a message should appear asking if user would like to restart VS Code for changes to take place.

Actual Behavior

Nothing changes, causing me to think that this setting is broken or I am changing the wrong setting.

Logs

OmniSharp log

There are no logs when any settings change.

C# log
