Title: Fix up title/slug handling on posts.

Refs #4323
- Remove any titleScratch observers that may be hanging
around on the post-settings-menu controller from previous posts.
- Change logic around when to regenerate slugs on posts that are
"(Untitled)" so that slug generation continues after slug no
longer resembles "untitled."
