Logs not helpful if book name is missing

[rridge532]

Currently, the logs aren't very helpful to see what book metadata is being fetched with fetching metadata for book". If seriesBookMeta.name is null/empty, the log isn't super helpful.

logger.info { "(${provider.providerName()}) fetching metadata for book ${seriesBookMeta.name}" }

It would be helpful to log the seriesBookMeta.id as is done with a similar log for series.
