Tabs don't update column counter

Repro:

1. Hit the tab key
2. Column count in gutter doesn't update

Forgive the GIF quality.

@alexandrudima not sure the fix is right, I can also change the editorStatus.ts to react on any types.

Indeed, I think the status bar should reflect the cursor state, regardless of the reason the cursor changed its state. So the fix should be made in editorStatus

Thanks for fixing this!
