remove ns event from games menu (see below).

turns out that the event is auto cleared when waited.
this meant that if sphaira handled the event before qlaunch got chance to handle it,
then qlaunch won't update when app records changed.

this can result in a gamecard not being mounted, deleted games still apearing, installed games
not being displayed etc...
