`languagesMap` not applied when used as `Workspace` setting

[aifrak]

Hi,

I have noticed recently that the extension is not working when comment-divider.languagesMap is used as Workspace setting.

Here an example of setting to reproduce the bug:

  "comment-divider.languagesMap": {
    "scss": ["//"]
  },

If I use comment-divider.languagesMap as User or Remote setting, the right comment character is used.

Extension version: v0.4.0
