The `XmlLibraryTest.removeBookByIdDropsTheReader` unit-test fails, demonstrating a bug in `kiwix::Library::removeBookById()`.
This fix makes the `XmlLibraryTest.removeBookByIdDropsTheReader` unit-test pass.
The new unit-test fails with a reason not expected before it was written. The `Library::filter()` operation returns a correct result after the call to `removeBookById()` (this was a surprise!) but it has a side-effect of re-adding an empty book with the id still surviving in the search DB (the emptiness of this re-created book doesn't allow it to pass the other filtering criteria, which explains why the result of `Library::filter()` is correct). Had to add a special check to the new unit-test against that hidden side-effect of `Library::removeBookById()` + `Library::filter()` combination.
This changes how the `XmlLibraryTest.removeBookByIdUpdatesTheSearchDB` unit-test fails.
This fix makes the `XmlLibraryTest.removeBookByIdUpdatesTheSearchDB` unit-test pass.

There was a problem hiding this comment.
This bug was introduced in #460 because Library::filter() is not declared const.

Fixes #478
I added a new test-suite
XmlLibraryTestso that I could make use of theLibrary::getReaderById()method (a library constructed from an OPDS stream doesn't contain local books).
