Include both `Album Count` and `Random` sortings for the Artists page.
This change also fixes the Artist search feature in Jellyfin, which was
broken because of an open issue on Jellyfin [1]. The current workaround
is to do the filtering locally after receiving all results from Jellyfin
API.
Also, as the Jellyfin API doesn't include a sorting option for
`AlbumCount`, we need to disable pagination when that option is
selected, to receive all artists, and run the sorting locally.
