fix(server): edit book metadata
Fixes save error in "ui/Pages/Bookmanager/WholeBookPage.js": passes the same arguments to "" that are passed by "BookChapterProcessed.js".
NB: "BookComponentPage.js" has the same "" definition which caused the error in "WholeBookPage.js" BUT the necessary arguments are not currently available to be passed to this component.
TODO: Test whether "BookComponentPage.js" produces this error.
