Fix/excessive logging (#848)

* Remove log of mangas to update

This logged the full manga data objects in the list with information that is not needed (e.g. description of a manga).
Once a manga gets updated via the updater, it gets logged, which should be enough

* Include manga id in updater log

* Use "toString" to log mangas

* Change "HttpLoggingInterceptor" level to "BASIC"
