Book titles do not sync for book sections

[davidvontamar]

Describe the issue
Book titles do not sync for book sections.

To Reproduce
Steps to reproduce the behavior:

1. Create a "Publication" property in your Notion destination database for Notero.
2. Sync book sections with book titles.
3. Book titles from Zotero are not synced into "Publication" property. Resulting in book sections without information about the book.

Expected behavior
Book titles are synced either into "Publication" property OR "Book Title" property.

Additional context
I find it odd that over 2K people did not complain so far about book sections not syncing their book titles.
Zotero 7 Beta on Debian.
