When adding a reply, we take a node at the end of the previous comment,
compare that comment's indentation level to the expected indentation level
of the reply, and add (or remove) that number of wrapper lists.
The existing code did not consider that comments may have lists within
them, and so the indentation of that node may not match the indentation
of the comment.

* Move modifier#getFullyCoveredWrapper to utils
* Use that method to find the node where we start searching for
template wrappers, rather than using endContainer
