Log path on lookup errors

If the lookup fails (due to a bad id in an nfo file for example), then
we had no indication of which directory failed, so the user can not
fix the problem.

Now we include the path in the error message such as:

MediaBrowser.Providers.TV.SeriesMetadataService: Error in
DummySeasonProvider for /media/x/y/z

and

MediaBrowser.Providers.Manager.ProviderManager:
TvdbSeriesImageProvider failed in GetImageInfos for type Series at
/media/x/y/z
