Title: [comment addon] Fix corner cases in uncommenting block comment

Currently, if the cursor is located in the very end or the very beginning of a block comment, like this:

```css
/* background-color: red; */|
```
The toggleComment command will not uncomment the block comment, but intuitively it should. This patch fixes this behavior.
