QT4: set sorting-connections by hand

Thisway playlist don't run sort when created (in case of you start vlc,
and don't set playlist visible then adding stuff. When you open playlist
it would sort the stuff).

Also remove showing sort-indicator incorrectly on start (don't show
it at all before user clicks to sort).
