Can't add followup comment to a previous comment

https://bugs.webkit.org/show_bug.cgi?id=104025

Reviewed by Adam Barth.

If we side-by-sidify a shared diff line, and then apply
a previous comment, we would incorrectly put the comment
on the Line instead of the LineContainer.

Also, get rid of global next_line_id to simplify testing.
