OTHER: Fix memleak and fixed small bug in hideEvent handlers

When promoe was minimized or on a different virtual desktop when it was quit,
the visible setting of playlist and equalizer was set to false.
So even when those two were visible before switching to a different desktop
they where set to closed when promoe was started the next time
