Video watchlist: sort alphabetically by name by default

The default sort put manual follows first (newest date_added), then airing
shows A–Z — so recently-followed shows like 'Welcome to Widows Bay' and 'From'
jumped to the top. A manual follow is no more special than an auto-added airing
show; default now sorts everything by name A–Z. 'added' (newest first) stays as
an opt-in sort.
