[Done] Please merge and update

[Nevena]

Hi, this book: Mis Lonliharts : is incorrectly added as a separate book, when it's actually a Serbian edition of this book: Miss Lonelyhearts

Could you please merge it?

The author's name is misspelled, it should be under Nathanael West

Other data needs to be updated as well:
- Title: Mis Lonliharts
(currently there is an unnecessary colon (:) after the title)
- Page count: 112
- Cover: https://lombooks.com/wp-content/uploa...

This is the publisher's website: https://lombooks.com/shop/v/vest-nata... - strangely, it doesn't have any info except for the title, author and the description. I took a photo of my physical copy in hope it will be of help for you to check the information: https://imgur.com/a/qELc1oa

Thank you in advance!
