Cleanup for Alexandre Dumas and AlexandreDumas

[Colleen]

There is a "duplicate" author page for Alexandre Dumas listed with the name without spaces (https://www.goodreads.com/author/show...). The only books listed under this erroneous profile are various sloppily cataloged editions of Count of Monte Cristo, most of which already exist in good form under the correct author profile.
