[#2842] Stop closing <poll-45123> placeholder tags

The HTML cleaner closes dangling tags (both at document end, and when closing tags mid-way), but exempts the HTML5 list of "empty" tags from that.

Once an entry with a poll is saved, the markup that was used to build the poll gets replaced with a <poll-nnn> placeholder, so the poll can't be subsequently modified. These placeholder tags are effectively empty tags, but the cleaner doesn't really treat them as special because it's not in charge of rendering them; LJ::Poll->expand_entry does that, and we call it after clean_event when we're rendering an entry.

Anyway, the cleaner was helpfully "closing" these placeholders, so, let's don't.
