Fixed: Bookmarks were not showing for newly added books from the OPDS stream.

* Removed books from `library.xml` if they no longer have any associated bookmarks, as keeping them is unnecessary and wastes resources and memory, while also increasing the time needed to load the library from storage.
* Fixed: The downloading online library progress was showing incorrect.
* Refactored the all unit test cases according to the new changes.
