fix(web): meta blocks after a cross-book range follow PHP's running book

After a "Multi" block the package names the book again ("…; John 3"),
which metaFromRef doubled into "John John 3"; PHP's piece was bare, so
live has "John 3". The book is now dropped when the request's piece had
none. Bare pieces after a leading cross-book range, which the package
drops, become PHP's getBook junk blocks (" 16:1" with no book and
verse_ids false, "3: 3:4"), as live returns them.
