Duplicate authors regarding Theodor Mommsen

[Thomas]

Hi!

https://www.goodreads.com/author/show... ,
https://www.goodreads.com/author/show...
and
https://www.goodreads.com/author/show...
is the same author. The two M version has 660 distinct works (compared to 3), and wikipedia (swedish, english and german at least) uses two M, so that's probably the correct one to keep.

Author https://www.goodreads.com/author/show... of the book
https://www.goodreads.com/book/show/9... should be deleted, as some misunderstanding made the author (full name: Christian Matthias Theodor Mommsen) end up as the two authors "Christian Matthias" and "Theodor Mommsen".
