[gnome-documents] Finalize removal of Books

[Christopher Davis <christopherdavis src gnome org>]

    Finalize removal of Books
    
    One thing left behind when removing Books was `org.gnome.Books.in`. We no longer need this. In addition,
    the removal of setting the "application" variable was missed, so it was never initialized, breaking 
Document's startup.
