Update metadata in source browse only if new data is not null (#962)

Browsing a source loads only a minimal representation of a manga which does not include some metadata. This metadata is only loaded when the specific manga gets fetched. Thus, when the extra metadata of a manga was already loaded, it got removed when browsing the source and a page response included this manga
