Video watchlist: strip dirty titles when sorting (leading-space fix)

'Holy Marvels with Dennis Quaid' is stored with a leading space in the shows
table, so the watchlist sort key fell to ' holy marvels…' — and a leading space
sorts before 'a', jumping it to the top. .strip() the sort key so dirty titles
sort by their real first letter.
